"This command generates installation rules for a project. "
"Rules specified by calls to this command within a source directory "
"are executed in order during installation. "
"The order across directories is not defined."
"\n"
"There are multiple signatures for this command. Some of them define "
"installation properties for files and targets. Properties common to "
"multiple signatures are covered here but they are valid only for "
"signatures that specify them.\n"
"DESTINATION arguments specify "
"the directory on disk to which a file will be installed. "
"If a full path (with a leading slash or drive letter) is given it "
"is used directly. If a relative path is given it is interpreted "
"relative to the value of CMAKE_INSTALL_PREFIX.\n"
"PERMISSIONS arguments specify permissions for installed files. "
"Valid permissions are "
"OWNER_READ, OWNER_WRITE, OWNER_EXECUTE, "
"GROUP_READ, GROUP_WRITE, GROUP_EXECUTE, "
"WORLD_READ, WORLD_WRITE, WORLD_EXECUTE, "
"SETUID, and SETGID. "
"Permissions that do not make sense on certain platforms are ignored "
"on those platforms.\n"
"The CONFIGURATIONS argument specifies a list of build configurations "
"for which the install rule applies (Debug, Release, etc.).\n"
"The COMPONENT argument specifies an installation component name "
"with which the install rule is associated, such as \"runtime\" or "
"\"development\". During component-specific installation only "
"install rules associated with the given component name will be "
"executed. During a full installation all components are installed.\n"
"The RENAME argument specifies a name for an installed file that "
"may be different from the original file. Renaming is allowed only "
"when a single file is installed by the command.\n"
"The OPTIONAL argument specifies that it is not an error if the "
"file to be installed does not exist. "
"\n"
"The TARGETS signature:\n"
" install(TARGETS targets... [EXPORT <export-name>]\n"
" [[ARCHIVE|LIBRARY|RUNTIME|FRAMEWORK|BUNDLE|\n"
" PRIVATE_HEADER|PUBLIC_HEADER|RESOURCE]\n"
" [DESTINATION <dir>]\n"
" [PERMISSIONS permissions...]\n"
" [CONFIGURATIONS [Debug|Release|...]]\n"
" [COMPONENT <component>]\n"
" [OPTIONAL] [NAMELINK_ONLY|NAMELINK_SKIP]\n"
" ] [...])\n"
"The TARGETS form specifies rules for installing targets from a "
"project. There are five kinds of target files that may be "
"installed: ARCHIVE, LIBRARY, RUNTIME, FRAMEWORK, and BUNDLE. "
"Executables are treated as RUNTIME targets, except that those "
"marked with the MACOSX_BUNDLE property are treated as BUNDLE "
"targets on OS X. "
"Static libraries are always treated as ARCHIVE targets. "
"Module libraries are always treated as LIBRARY targets. "
"For non-DLL platforms shared libraries are treated as LIBRARY "
"targets, except that those marked with the FRAMEWORK property "
"are treated as FRAMEWORK targets on OS X. "
"For DLL platforms the DLL part of a shared library is treated as "
"a RUNTIME target and the corresponding import library is treated as "
"an ARCHIVE target. "
"All Windows-based systems including Cygwin are DLL platforms. "
"The ARCHIVE, LIBRARY, RUNTIME, and FRAMEWORK "
"arguments change the type of target to which the subsequent "
"properties "
"apply. If none is given the installation properties apply to "
"all target types. If only one is given then only targets of that "
"type will be installed (which can be used to install just a DLL or "
"just an import library)."
"\n"
"The PRIVATE_HEADER, PUBLIC_HEADER, and RESOURCE arguments cause "
"subsequent properties to be applied to installing a FRAMEWORK "
"shared library target's associated files on non-Apple platforms. "
"Rules defined by these arguments are ignored on Apple platforms "
"because the associated files are installed into the appropriate "
"locations inside the framework folder. "
"See documentation of the PRIVATE_HEADER, PUBLIC_HEADER, and RESOURCE "
"target properties for details."
"\n"
"Either NAMELINK_ONLY or NAMELINK_SKIP may be specified as a LIBRARY "
"option. "
"On some platforms a versioned shared library has a symbolic link "
"such as\n"
" lib<name>.so -> lib<name>.so.1\n"
"where \"lib<name>.so.1\" is the soname of the library and "
"\"lib<name>.so\" is a \"namelink\" allowing linkers to find the "
"library when given \"-l<name>\". "
"The NAMELINK_ONLY option causes installation of only the namelink "
"when a library target is installed. "
"The NAMELINK_SKIP option causes installation of library files other "
"than the namelink when a library target is installed. "
"When neither option is given both portions are installed. "
"On platforms where versioned shared libraries do not have namelinks "
"or when a library is not versioned the NAMELINK_SKIP option installs "
"the library and the NAMELINK_ONLY option installs nothing. "
"See the VERSION and SOVERSION target properties for details on "
"creating versioned shared libraries."
"\n"
"One or more groups of properties may be specified in a single call "
"to the TARGETS form of this command. A target may be installed more "
"than once to different locations. Consider hypothetical "
"targets \"myExe\", \"mySharedLib\", and \"myStaticLib\". The code\n"
" install(TARGETS myExe mySharedLib myStaticLib\n"
" RUNTIME DESTINATION bin\n"
" LIBRARY DESTINATION lib\n"
" ARCHIVE DESTINATION lib/static)\n"
" install(TARGETS mySharedLib DESTINATION /some/full/path)\n"
"will install myExe to <prefix>/bin and myStaticLib to "
"<prefix>/lib/static. "
"On non-DLL platforms mySharedLib will be installed to <prefix>/lib "
"and /some/full/path. On DLL platforms the mySharedLib DLL will be "
"installed to <prefix>/bin and /some/full/path and its import library "
"will be installed to <prefix>/lib/static and /some/full/path. "
"On non-DLL platforms mySharedLib will be installed to <prefix>/lib "
"and /some/full/path."
"\n"
"The EXPORT option associates the installed target files with an "
"export called <export-name>. "
"It must appear before any RUNTIME, LIBRARY, or ARCHIVE options. "
"To actually install the export file itself, call install(EXPORT). "
"See documentation of the install(EXPORT ...) signature below for "
"details."
"\n"
"Installing a target with EXCLUDE_FROM_ALL set to true has "
"undefined behavior."
"\n"
"The FILES signature:\n"
" install(FILES files... DESTINATION <dir>\n"
" [PERMISSIONS permissions...]\n"
" [CONFIGURATIONS [Debug|Release|...]]\n"
" [COMPONENT <component>]\n"
" [RENAME <name>] [OPTIONAL])\n"
"The FILES form specifies rules for installing files for a "
"project. File names given as relative paths are interpreted with "
"respect to the current source directory. Files installed by this "
"form are by default given permissions OWNER_WRITE, OWNER_READ, "
"GROUP_READ, and WORLD_READ if no PERMISSIONS argument is given."
"\n"
"The PROGRAMS signature:\n"
" install(PROGRAMS files... DESTINATION <dir>\n"
" [PERMISSIONS permissions...]\n"
" [CONFIGURATIONS [Debug|Release|...]]\n"
" [COMPONENT <component>]\n"
" [RENAME <name>] [OPTIONAL])\n"
"The PROGRAMS form is identical to the FILES form except that the "
"default permissions for the installed file also include "
"OWNER_EXECUTE, GROUP_EXECUTE, and WORLD_EXECUTE. "
"This form is intended to install programs that are not targets, "
"such as shell scripts. Use the TARGETS form to install targets "
"built within the project."
"\n"
"The DIRECTORY signature:\n"
" install(DIRECTORY dirs... DESTINATION <dir>\n"
" [FILE_PERMISSIONS permissions...]\n"
" [DIRECTORY_PERMISSIONS permissions...]\n"
" [USE_SOURCE_PERMISSIONS] [OPTIONAL]\n"
" [CONFIGURATIONS [Debug|Release|...]]\n"
" [COMPONENT <component>] [FILES_MATCHING]\n"
" [[PATTERN <pattern> | REGEX <regex>]\n"
" [EXCLUDE] [PERMISSIONS permissions...]] [...])\n"
"The DIRECTORY form installs contents of one or more directories "
"to a given destination. "
"The directory structure is copied verbatim to the destination. "
"The last component of each directory name is appended to the "
"destination directory but a trailing slash may be used to "
"avoid this because it leaves the last component empty. "
"Directory names given as relative paths are interpreted with "
"respect to the current source directory. "
"If no input directory names are given the destination directory "
"will be created but nothing will be installed into it. "
"The FILE_PERMISSIONS and DIRECTORY_PERMISSIONS options specify "
"permissions given to files and directories in the destination. "
"If USE_SOURCE_PERMISSIONS is specified and FILE_PERMISSIONS is not, "
"file permissions will be copied from the source directory structure. "
"If no permissions are specified files will be given the default "
"permissions specified in the FILES form of the command, and the "
"directories will be given the default permissions specified in the "
"PROGRAMS form of the command.\n"
"Installation of directories may be controlled with fine granularity "
"using the PATTERN or REGEX options. These \"match\" options specify a "
"globbing pattern or regular expression to match directories or files "
"encountered within input directories. They may be used to apply "
"certain options (see below) to a subset of the files and directories "
"encountered. "
"The full path to each input file or directory "
"(with forward slashes) is matched against the expression. "
"A PATTERN will match only complete file names: the portion of the "
"full path matching the pattern must occur at the end of the file name "
"and be preceded by a slash. "
"A REGEX will match any portion of the full path but it may use "
"'/' and '$' to simulate the PATTERN behavior. "
"By default all files and directories are installed whether "
"or not they are matched. "
"The FILES_MATCHING option may be given before the first match option "
"to disable installation of files (but not directories) not matched by "
"any expression. For example, the code\n"
" install(DIRECTORY src/ DESTINATION include/myproj\n"
" FILES_MATCHING PATTERN \"*.h\")\n"
"will extract and install header files from a source tree.\n"
"Some options may follow a PATTERN or REGEX expression and are "
"applied only to files or directories matching them. "
"The EXCLUDE option will skip the matched file or directory. "
"The PERMISSIONS option overrides the permissions setting for the "
"matched file or directory. "
"For example the code\n"
" install(DIRECTORY icons scripts/ DESTINATION share/myproj\n"
" PATTERN \"CVS\" EXCLUDE\n"
" PATTERN \"scripts/*\"\n"
" PERMISSIONS OWNER_EXECUTE OWNER_WRITE OWNER_READ\n"
" GROUP_EXECUTE GROUP_READ)\n"
"will install the icons directory to share/myproj/icons and the "
"scripts directory to share/myproj. The icons will get default file "
"permissions, the scripts will be given specific permissions, and "
"any CVS directories will be excluded."
"\n"
"The SCRIPT and CODE signature:\n"
" install([[SCRIPT <file>] [CODE <code>]] [...])\n"
"The SCRIPT form will invoke the given CMake script files during "
"installation. If the script file name is a relative path "
"it will be interpreted with respect to the current source directory. "
"The CODE form will invoke the given CMake code during installation. "
"Code is specified as a single argument inside a double-quoted string. "
"For example, the code\n"
" install(CODE \"MESSAGE(\\\"Sample install message.\\\")\")\n"
"will print a message during installation.\n"
""
"The EXPORT signature:\n"
" install(EXPORT <export-name> DESTINATION <dir>\n"
" [NAMESPACE <namespace>] [FILE <name>.cmake]\n"
" [PERMISSIONS permissions...]\n"
" [CONFIGURATIONS [Debug|Release|...]]\n"
" [COMPONENT <component>])\n"
"The EXPORT form generates and installs a CMake file containing code "
"to import targets from the installation tree into another project. "
"Target installations are associated with the export <export-name> "
"using the EXPORT option of the install(TARGETS ...) signature "
"documented above. The NAMESPACE option will prepend <namespace> to "
"the target names as they are written to the import file. "
"By default the generated file will be called <export-name>.cmake but "
"the FILE option may be used to specify a different name. The value "
"given to the FILE option must be a file name with the \".cmake\" "
"extension. "
"If a CONFIGURATIONS option is given then the file will only be "
"installed when one of the named configurations is installed. "
"Additionally, the generated import file will reference only the "
"matching target configurations. "
"If a COMPONENT option is specified that does not match that given "
"to the targets associated with <export-name> the behavior is "
"undefined. "
"If a library target is included in the export but "
"a target to which it links is not included the behavior is "
"unspecified."
"\n"
"The EXPORT form is useful to help outside projects use targets built "
"and installed by the current project. For example, the code\n"
" install(TARGETS myexe EXPORT myproj DESTINATION bin)\n"
" install(EXPORT myproj NAMESPACE mp_ DESTINATION lib/myproj)\n"
"will install the executable myexe to <prefix>/bin and code to import "
"it in the file \"<prefix>/lib/myproj/myproj.cmake\". "
"An outside project may load this file with the include command "
"and reference the myexe executable from the installation tree using "
"the imported target name mp_myexe as if the target were built "
"in its own tree."
"\n"
"NOTE: This command supercedes the INSTALL_TARGETS command and the "
"target properties PRE_INSTALL_SCRIPT and POST_INSTALL_SCRIPT. "
"It also replaces the FILES forms of the INSTALL_FILES and "
"INSTALL_PROGRAMS commands. "
"The processing order of these install rules relative to those "
"generated by INSTALL_TARGETS, INSTALL_FILES, and INSTALL_PROGRAMS "
"commands is not defined.\n"
