Since most of the find modules use the `<PackageName>_FOUND` result
variables, this now also syncs it for the FindPkgConfig module. The
`PkgConfig_FOUND` result variable is available since CMake 3.3 and
contains the same value. There is also `PKGCONFIG_FOUND` result variable
automatically set with the same value but for simplicity isn't
documented. The uppercased `<PACKAGENAME>_FOUND` result variables set by
find modules are also considered legacy variables.
Unquote pkg-config output if they are printed within quotes. pkgconf
<1.5.1 and classic pkg-config <0.29.1 prints quoted variables without
unquoting them, this breaks returning variables with multiple values
as a list behavior of CMake.
Add a new test case for pkg_get_variable with multiple values to test
list behavior and backslash escaped spaces within variable values.

The Windows implementation of these tests have been found to not
handle Windows paths and path separators properly in a number of
areas. The whole approach taken in these tests appears dubious, so
they may need to be significantly rewritten. Disable them until then
so we don't get false positives.
Issue: #22031
Older versions of pkg-config (e.g. 0.21 and 0.22) do not
handle correctly spaces in paths specified in .pc files.
It breaks RunCMake.FindPkgConfig test, if CMake is built
inside path containing spaces. In this case, we check if
we're inside such path, and if pkg-config is broken; and
if both are true, test is to be skipped.
Revert commit 020976d637 (FindPkgConfig: Populate
_STATIC_LINK_LIBRARIES. Add STATIC_TARGET., 2021-12-31,
v3.24.0-rc1~105^2). Several regressions have been reported.
Revert the feature pending further discussion and design work.
Issue: #21714Fixes: #23642
Add LINK_LIBRARIES test to demonstrate static linking of transitive
dependencies.
Add STATIC_TARGET argument to pkg_check_modules() and pkg_search_module().
Influences the properties of target produced by IMPORTED_TARGET.
When enabled: target's properties will be populated from <XXX>_STATIC_*
variables instead of from <XXX>_* variables.
Update existing tests concerning properties of targets produced via
IMPORTED_TARGET, to test STATIC_TARGET variant too.
Update existing tests concerning <XXX>_* variables to test <XXX>_STATIC_*
variables too.
Breaking changes to pkg_check_modules() and pkg_search_module():
- Variables CMAKE_FIND_LIBRARY_PREFIXES and CMAKE_FIND_LIBRARY_SUFFIXES can no
longer be used to influence library lookup (i.e. the internal call to
find_library()), because FindPkgConfig now internally relies on these
variables to differentiate between shared and static library lookup.
Prefer CMAKE_SHARED_LIBRARY_PREFIX + CMAKE_SHARED_LIBRARY_SUFFIX, or
CMAKE_STATIC_LIBRARY_PREFIX + CMAKE_STATIC_LIBRARY_SUFFIX, depending on
whether you wish to impact static or shared lookup.
- <XXX>_LINK_LIBRARIES will now be populated only with libraries
located via CMAKE_SHARED_LIBRARY_PREFIX + CMAKE_SHARED_LIBRARY_SUFFIX match
- <XXX>_STATIC_LIBRARIES now processes -framework options
- <XXX>_STATIC_LDFLAGS_OTHER now processes -framework options
- <XXX>_STATIC_CFLAGS_OTHER now processes -isystem options
- <XXX>_STATIC_INCLUDE_DIRS now processes -isystem options
Fixes: #21714
Treat backslash-escaped spaces as "space within argument" rather than
"space delimiting arguments".
Update our `FindPkgConfig_LIBRARY_PATH` test case to escape spaces in
the path, and run it unconditionally.
Tell `pkg-config --libs` not to filter out `-L` flags for entries of
`PKG_CONFIG_SYSTEM_LIBRARY_PATH` (and `LIBRARY_PATH` for `pkgconf`).
We should always search everywhere the `.pc` file expects.
Fixes: #22148
It's common for some people to use the PKG_CONFIG environment variable
to not only load a custom pkg-config/pkgconf but also to load some
default arguments such as `--static` or `--keep-system-libs` which often
worked since shell scripts would call `$PKG_CONFIG --libs pkg` without
quotes, but this breaks FindPkgConfig since it uses the full string as
`argv[0]` and might try looking for a binary called `pkgconf --static`,
instead of looking for `pkgconf` and adding `--static` as the `argv[1]`
Additionally adds RunCMake.FindPkgConfig ARGN test case

When running `pkg_search_module`, it may be useful to get the matching
module name in order to run `pkg_get_variable`.
`pkg_search_module` now defines `<prefix>_MODULE_NAME` which contains
the first matching module name.
Fixes: #19648
The CMAKE_FRAMEWORK_PATH and CMAKE_APPBUNDLE_PATH cache variables are
supposed to be used to generate the extra paths passed to pkg-config,
but instead the CMAKE_PREFIX_PATH variable is used.
This bug was introduced by the refactor in commit v3.1.0-rc1~747^2~1.
Use CMAKE_PREFIX_PATH, CMAKE_FRAMEWORK_PATH, and CMAKE_APPBUNDLE_PATH
cache and environment variables to extend PKG_CONFIG_PATH before calling
pkg-config.
In each of the path in these variables it searches for lib/pkgconfig.
Then, depending on the system, it searches for
lib/${CMAKE_LIBRARY_ARCHITECTURE}/pkgconfig (debian) or for
lib64/pkgconfig (other 64 bit unixes). If any of these path is found,
it is appended to the PKG_CONFIG_PATH enviromnent variable.
Add two new arguments to the pkg_check_module and pkg_search_module
macro, NO_CMAKE_PATH and NO_CMAKE_ENVIRONMENT_PATH. The new signature
are therefore:
pkg_check_modules(<PREFIX> [REQUIRED] [QUIET]
[NO_CMAKE_PATH] [NO_CMAKE_ENVIRONMENT_PATH]
<MODULE> [<MODULE>]*)
pkg_search_module(<PREFIX> [REQUIRED] [QUIET]
[NO_CMAKE_PATH] [NO_CMAKE_ENVIRONMENT_PATH]
<MODULE> [<MODULE>]*)
By default, if CMAKE_MINIMUM_REQUIRED_VERSION is 3.1 or later (in
order to keep compatibility with the previous behavior), or if
PKG_CONFIG_USE_CMAKE_PREFIX_PATH is set, the CMAKE_PREFIX_PATH,
CMAKE_FRAMEWORK_PATH, and CMAKE_APPBUNDLE_PATH cache and environment
variables will be added to pkgconfig search path.
The NO_CMAKE_PATH and NO_CMAKE_ENVIRONMENT_PATH arguments disable this
behavior for the cache variables and the environment variables,
respectively, similarly to the find_package() command.
