Alex Neundorf 33338781db Log the required package version and major improvement to FeatureSummary 
find_package() now also stores the required version automatically, so it
can be used by FeatureSummary.cmake.
This was one of the requested features for setting up nightly builds
for KDE, since with this functionality it will be possible to write
a file at the end of each project which lists all required packages
and their versions. This file could then be compared for equality
with an older one and if something has changed the build maintainer
can be emailed.

In FeatureSummary.cmake there is now a new function feature_summary(),
which also allows to print the log to a file or into a variable.
It also allows to specify whether to append to a file or to write a new
one, and what information to log.

Docs are still missing.

"The QUIET option disables messages if the package cannot be found. "
"The REQUIRED option stops processing with an error message if the "
"package cannot be found. "
"A package-specific list of components may be listed after the "
"REQUIRED option or after the COMPONENTS option if no REQUIRED "
"option is given. "
"The [version] argument requests a version with which the package found "
"should be compatible (format is major[.minor[.patch[.tweak]]]). "
"The EXACT option requests that the version be matched exactly. "
"If no [version] is given to a recursive invocation inside a "
"find-module, the [version] and EXACT arguments are forwarded "
"automatically from the outer call. "
"Version support is currently provided only on a package-by-package "
"basis (details below).\n"
"User code should generally look for packages using the above simple "
"signature. The remainder of this command documentation specifies the "
"full command signature and details of the search process. Project "
"maintainers wishing to provide a package to be found by this command "
"are encouraged to read on.\n"
"The command has two modes by which it searches for packages: "
"\"Module\" mode and \"Config\" mode. "
"Module mode is available when the command is invoked with the above "
"reduced signature. "
"CMake searches for a file called \"Find<package>.cmake\" in "
"the CMAKE_MODULE_PATH followed by the CMake installation. "
"If the file is found, it is read and processed by CMake. "
"It is responsible for finding the package, checking the version, "
"and producing any needed messages. "
"Many find-modules provide limited or no support for versioning; "
"check the module documentation. "
"If no module is found the command proceeds to Config mode.\n"
"The complete Config mode command signature is:\n"
" find_package(<package> [version] [EXACT] [QUIET]\n"
" [[REQUIRED|COMPONENTS] [components...]] [NO_MODULE]\n"
" [NO_POLICY_SCOPE]\n"
" [NAMES name1 [name2 ...]]\n"
" [CONFIGS config1 [config2 ...]]\n"
" [HINTS path1 [path2 ... ]]\n"
" [PATHS path1 [path2 ... ]]\n"
" [PATH_SUFFIXES suffix1 [suffix2 ...]]\n"
" [NO_DEFAULT_PATH]\n"
" [NO_CMAKE_ENVIRONMENT_PATH]\n"
" [NO_CMAKE_PATH]\n"
" [NO_SYSTEM_ENVIRONMENT_PATH]\n"
" [NO_CMAKE_PACKAGE_REGISTRY]\n"
" [NO_CMAKE_BUILDS_PATH]\n"
" [NO_CMAKE_SYSTEM_PATH]\n"
" [CMAKE_FIND_ROOT_PATH_BOTH |\n"
" ONLY_CMAKE_FIND_ROOT_PATH |\n"
" NO_CMAKE_FIND_ROOT_PATH])\n"
"The NO_MODULE option may be used to skip Module mode explicitly. "
"It is also implied by use of options not specified in the reduced "
"signature. "
"\n"
"Config mode attempts to locate a configuration file provided by the "
"package to be found. A cache entry called <package>_DIR is created to "
"hold the directory containing the file. "
"By default the command searches for a package with the name <package>. "
"If the NAMES option is given the names following it are used instead "
"of <package>. "
"The command searches for a file called \"<name>Config.cmake\" or "
"\"<lower-case-name>-config.cmake\" for each name specified. "
"A replacement set of possible configuration file names may be given "
"using the CONFIGS option. "
"The search procedure is specified below. Once found, the configuration "
"file is read and processed by CMake. Since the file is provided by the "
"package it already knows the location of package contents. "
"The full path to the configuration file is stored in the cmake "
"variable <package>_CONFIG."
"\n"
"If the package configuration file cannot be found CMake "
"will generate an error describing the problem unless the QUIET "
"argument is specified. If REQUIRED is specified and the package "
"is not found a fatal error is generated and the configure step stops "
"executing. If <package>_DIR has been set to a directory not containing "
"a configuration file CMake will ignore it and search from scratch."
"\n"
"When the [version] argument is given Config mode will only find a "
"version of the package that claims compatibility with the requested "
"version (format is major[.minor[.patch[.tweak]]]). "
"If the EXACT option is given only a version of the package claiming "
"an exact match of the requested version may be found. "
"CMake does not establish any convention for the meaning of version "
"numbers. "
"Package version numbers are checked by \"version\" files provided by "
"the packages themselves. "
"For a candidate package configuration file \"<config-file>.cmake\" the "
"corresponding version file is located next to it and named either "
"\"<config-file>-version.cmake\" or \"<config-file>Version.cmake\". "
"If no such version file is available then the configuration file "
"is assumed to not be compatible with any requested version. "
"When a version file is found it is loaded to check the requested "
"version number. "
"The version file is loaded in a nested scope in which the following "
"variables have been defined:\n"
" PACKAGE_FIND_NAME = the <package> name\n"
" PACKAGE_FIND_VERSION = full requested version string\n"
" PACKAGE_FIND_VERSION_MAJOR = major version if requested, else 0\n"
" PACKAGE_FIND_VERSION_MINOR = minor version if requested, else 0\n"
" PACKAGE_FIND_VERSION_PATCH = patch version if requested, else 0\n"
" PACKAGE_FIND_VERSION_TWEAK = tweak version if requested, else 0\n"
" PACKAGE_FIND_VERSION_COUNT = number of version components, 0 to 4\n"
"The version file checks whether it satisfies the requested version "
"and sets these variables:\n"
" PACKAGE_VERSION = full provided version string\n"
" PACKAGE_VERSION_EXACT = true if version is exact match\n"
" PACKAGE_VERSION_COMPATIBLE = true if version is compatible\n"
" PACKAGE_VERSION_UNSUITABLE = true if unsuitable as any version\n"
"These variables are checked by the find_package command to determine "
"whether the configuration file provides an acceptable version. "
"They are not available after the find_package call returns. "
"If the version is acceptable the following variables are set:\n"
" <package>_VERSION = full provided version string\n"
" <package>_VERSION_MAJOR = major version if provided, else 0\n"
" <package>_VERSION_MINOR = minor version if provided, else 0\n"
" <package>_VERSION_PATCH = patch version if provided, else 0\n"
" <package>_VERSION_TWEAK = tweak version if provided, else 0\n"
" <package>_VERSION_COUNT = number of version components, 0 to 4\n"
"and the corresponding package configuration file is loaded. "
"When multiple package configuration files are available whose version "
"files claim compatibility with the version requested it is unspecified "
"which one is chosen. "
"No attempt is made to choose a highest or closest version number."
"\n"
"Config mode provides an elaborate interface and search procedure. "
"Much of the interface is provided for completeness and for use "
"internally by find-modules loaded by Module mode. "
"Most user code should simply call\n"
" find_package(<package> [major[.minor]] [EXACT] [REQUIRED|QUIET])\n"
"in order to find a package. Package maintainers providing CMake "
"package configuration files are encouraged to name and install "
"them such that the procedure outlined below will find them "
"without requiring use of additional options."
"\n"
"CMake constructs a set of possible installation prefixes for the "
"package. Under each prefix several directories are searched for a "
"configuration file. The tables below show the directories searched. "
"Each entry is meant for installation trees following Windows (W), "
"UNIX (U), or Apple (A) conventions.\n"
" <prefix>/ (W)\n"
" <prefix>/(cmake|CMake)/ (W)\n"
" <prefix>/<name>*/ (W)\n"
" <prefix>/<name>*/(cmake|CMake)/ (W)\n"
" <prefix>/(share|lib)/cmake/<name>*/ (U)\n"
" <prefix>/(share|lib)/<name>*/ (U)\n"
" <prefix>/(share|lib)/<name>*/(cmake|CMake)/ (U)\n"
"On systems supporting OS X Frameworks and Application Bundles "
"the following directories are searched for frameworks or bundles "
"containing a configuration file:\n"
" <prefix>/<name>.framework/Resources/ (A)\n"
" <prefix>/<name>.framework/Resources/CMake/ (A)\n"
" <prefix>/<name>.framework/Versions/*/Resources/ (A)\n"
" <prefix>/<name>.framework/Versions/*/Resources/CMake/ (A)\n"
" <prefix>/<name>.app/Contents/Resources/ (A)\n"
" <prefix>/<name>.app/Contents/Resources/CMake/ (A)\n"
"In all cases the <name> is treated as case-insensitive and corresponds "
"to any of the names specified (<package> or names given by NAMES). "
"If PATH_SUFFIXES is specified the suffixes are appended to each "
"(W) or (U) directory entry one-by-one.\n"
"This set of directories is intended to work in cooperation with "
"projects that provide configuration files in their installation trees. "
"Directories above marked with (W) are intended for installations on "
"Windows where the prefix may point at the top of an application's "
"installation directory. Those marked with (U) are intended for "
"installations on UNIX platforms where the prefix is shared by "
"multiple packages. This is merely a convention, so all (W) and (U) "
"directories are still searched on all platforms. "
"Directories marked with (A) are intended for installations on "
"Apple platforms. The cmake variables CMAKE_FIND_FRAMEWORK and "
"CMAKE_FIND_APPBUNDLE determine the order of preference "
"as specified below.\n"
"The set of installation prefixes is constructed using the following "
"steps. If NO_DEFAULT_PATH is specified all NO_* options are enabled.\n"
"1. Search paths specified in cmake-specific cache variables. "
"These are intended to be used on the command line with a -DVAR=value. "
"This can be skipped if NO_CMAKE_PATH is passed.\n"
" CMAKE_PREFIX_PATH\n"
" CMAKE_FRAMEWORK_PATH\n"
" CMAKE_APPBUNDLE_PATH\n"
"2. Search paths specified in cmake-specific environment variables. "
"These are intended to be set in the user's shell configuration. "
"This can be skipped if NO_CMAKE_ENVIRONMENT_PATH is passed.\n"
" <package>_DIR\n"
" CMAKE_PREFIX_PATH\n"
" CMAKE_FRAMEWORK_PATH\n"
" CMAKE_APPBUNDLE_PATH\n"
"3. Search paths specified by the HINTS option. "
"These should be paths computed by system introspection, such as a "
"hint provided by the location of another item already found. "
"Hard-coded guesses should be specified with the PATHS option.\n"
"4. Search the standard system environment variables. "
"This can be skipped if NO_SYSTEM_ENVIRONMENT_PATH is passed. "
"Path entries ending in \"/bin\" or \"/sbin\" are automatically "
"converted to their parent directories.\n"
" PATH\n"
"5. Search project build trees recently configured in a CMake GUI. "
"This can be skipped if NO_CMAKE_BUILDS_PATH is passed. "
"It is intended for the case when a user is building multiple "
"dependent projects one after another.\n"
"6. Search paths stored in the CMake user package registry. "
"This can be skipped if NO_CMAKE_PACKAGE_REGISTRY is passed. "
"Paths are stored in the registry when CMake configures a project "
"that invokes export(PACKAGE <name>). "
"See the export(PACKAGE) command documentation for more details."
"\n"
"7. Search cmake variables defined in the Platform files "
"for the current system. This can be skipped if NO_CMAKE_SYSTEM_PATH "
"is passed.\n"
" CMAKE_SYSTEM_PREFIX_PATH\n"
" CMAKE_SYSTEM_FRAMEWORK_PATH\n"
" CMAKE_SYSTEM_APPBUNDLE_PATH\n"
"8. Search paths specified by the PATHS option. "
"These are typically hard-coded guesses.\n"
