Raw Normal View History

Simplify CMake per-source license notices Per-source copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong. Precise contributor information is already maintained automatically by the version control tool. Ultimately it is the receiver of a file who is responsible for determining its licensing status, and per-source notices are merely a convenience. Therefore it is simpler and more accurate for each source to have a generic notice of the license name and references to more detailed information on copyright holders and full license terms. Our `Copyright.txt` file now contains a list of Contributors whose names appeared source-level copyright notices. It also references version control history for more precise information. Therefore we no longer need to spell out the list of Contributors in each source file notice. Replace CMake per-source copyright/license notice headers with a short description of the license and links to `Copyright.txt` and online information available from "https://cmake.org/licensing". The online URL also handles cases of modules being copied out of our source into other projects, so we can drop our notices about replacing links with full license text. Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority of the replacements mechanically. Manually fix up shebang lines and trailing newlines in a few files. Manually update the notices in a few files that the script does not handle.

ENH: add documentation support for modules
2005-12-14 18:51:08 +00:00
Convert CMake non-find modules to BSD License This adds copyright/license notification blocks CMake's non-find modules. Most of the modules had no notices at all. Some had notices referring to the BSD license already. This commit normalizes existing notices and adds missing notices.

ENH: more uniform approach to enable language, one step closer to being able to enable a language without modifing cmake source code
2004-08-26 18:55:55 +00:00
# This file sets the basic flags for the C language in CMake.
# It also loads the available platform file for the system-compiler
# if it exists.
ENH: also load a processor-specific file if exists -also try the basename file if the compiler id file doesn't exist -don't rely so much on the CMAKE_TOOLCHAIN_FILE Alex

include(CMakeLanguageInformation)
ENH: split cmGlobalGenerator::SetLanguageEnabled() in two parts, where the second part copies the values from the cmake variables into internal maps. So this can now be done after the compiler-specific information has been loaded, which can now overwrite more settings. Alex

set(_INCLUDED_FILE 0)
Reset platform/compiler info status for each language In each CMake<lang>Information.cmake file we use an _INCLUDED_FILE variable to track whether a compiler information file has been loaded. Reset this variable for each language. This fixes Fortran under VS generators with the Intel plugin. Previously the variable would be left set true from C and C++ and then Fortran would not load old-style files like Platform/Windows-ifort.

Use work-around from bug 4772 for C++ and Fortran The commit "fix for bug 4772" added a work-around to CMakeCInformation for platform config files that put compiler information in the system file (like SunOS flags for GCC). This commit adds the same work-around for CXX and Fortran. It is necessary to support enabling these languages separately from C in other subdirectories. The commit "Avoid (Unix|Windows)Paths.cmake multiple include" added include blockers that prevent the files from multiple inclusion, so it is safe to include the system information files from every language. See issue #4772 and issue #9656.

Support building shared libraries or modules without soname (#13155) Add a boolean target property NO_SONAME which may be used to disable soname for the specified shared library or module even if the platform supports it. This property should be useful for private shared libraries or various plugins which live in private directories and have not been designed to be found or loaded globally. Replace references to <CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG> and hard-coded -install_name flags with a conditional <SONAME_FLAG> which is expanded to the value of the CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG definition as long as soname supports is enabled for the target in question. Keep expanding CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG in rules in case third party projects still use it. Such projects would not yet use NO_SONAME so the adjacent <TARGET_SONAME> will always be expanded. Make <TARGET_INSTALLNAME_DIR> NO_SONAME aware as well. Since -install_name is soname on OS X, this should not be a problem if this variable is expanded only if soname is enabled. The Ninja generator performs rule variable substitution only once globally per rule to put its own placeholders. Final substitution is performed by ninja at build time. Therefore we cannot conditionally replace the soname placeholders on a per-target basis. Rather than omitting $SONAME from rules.ninja, simply do not write its contents for targets which have NO_SONAME. Since 3 variables are affected by NO_SONAME ($SONAME, $SONAME_FLAG, $INSTALLNAME_DIR), set them only if soname is enabled.

ENH: Implement linking with paths to library files instead of -L and -l separation. See bug #3832 - This is purely an implementation improvement. No interface has changed. - Create cmComputeLinkInformation class - Move and re-implement logic from: cmLocalGenerator::ComputeLinkInformation cmOrderLinkDirectories - Link libraries to targets with their full path (if it is known) - Dirs specified with link_directories command still added with -L - Make link type specific to library names without paths (name libfoo.a without path becomes -Wl,-Bstatic -lfoo) - Make directory ordering specific to a runtime path computation feature (look for conflicting SONAMEs instead of library names) - Implement proper rpath support on HP-UX and AIX.

ENH: Pass dependent library search path to linker on some platforms. - Move runtime path ordering out of cmComputeLinkInformation into its own class cmOrderRuntimeDirectories. - Create an instance of cmOrderRuntimeDirectories for runtime path ordering and another instance for dependent library path ordering. - Replace CMAKE_DEPENDENT_SHARED_LIBRARY_MODE with explicit CMAKE_LINK_DEPENDENT_LIBRARY_FILES boolean. - Create CMAKE_LINK_DEPENDENT_LIBRARY_DIRS boolean. - Create variables to specify -rpath-link flags: CMAKE_SHARED_LIBRARY_RPATH_LINK_<LANG>_FLAG CMAKE_EXECUTABLE_RPATH_LINK_<LANG>_FLAG - Enable -rpath-link flag on Linux and QNX. - Documentation and error message updates
