FindPkgConfig: Extend PKG_CONFIG_PATH using CMake variables (#12926)
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.

FindPkgConfig: Extend PKG_CONFIG_PATH using CMake variables (#12926)
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

FindPkgConfig: Extend PKG_CONFIG_PATH using CMake variables (#12926)
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.

<moduleSpec> [<moduleSpec>...])
|
|
|
|
|
|
|
|
|
|
When the ``REQUIRED`` argument is given, the command will fail with an error
|
|
|
|
|
if module(s) could not be found.
|
|
|
|
|
|
|
|
|
|
When the ``QUIET`` argument is given, no status messages will be printed.
|
|
|
|
|
|
|
|
|
|
By default, if :variable:`CMAKE_MINIMUM_REQUIRED_VERSION` is 3.1 or
|
|
|
|
|
later, or if :variable:`PKG_CONFIG_USE_CMAKE_PREFIX_PATH` is set to a
|
|
|
|
|
boolean ``True`` value, then the :variable:`CMAKE_PREFIX_PATH`,
|
|
|
|
|
:variable:`CMAKE_FRAMEWORK_PATH`, and :variable:`CMAKE_APPBUNDLE_PATH` cache
|
|
|
|
|
and environment variables will be added to the ``pkg-config`` search path.
|
|
|
|
|
The ``NO_CMAKE_PATH`` and ``NO_CMAKE_ENVIRONMENT_PATH`` arguments
|
|
|
|
|
disable this behavior for the cache variables and environment variables
|
|
|
|
|
respectively.
|
|
|
|
|
|
|
|
|
|
The ``IMPORTED_TARGET`` argument will create an imported target named
|
|
|
|
|
``PkgConfig::<prefix>`` that can be passed directly as an argument to
|
2018-07-05 16:20:26 +00:00
|
|
|
:command:`target_link_libraries`. The ``GLOBAL`` argument will make the
|
|
|
|
|
imported target available in global scope.

Each ``<moduleSpec>`` can be either a bare module name or it can be a
|
|
|
|
|
module name with a version constraint (operators ``=``, ``<``, ``>``,
|
|
|
|
|
``<=`` and ``>=`` are supported). The following are examples for a module
|
2018-10-10 21:03:31 +00:00
|
|
|
named ``foo`` with various constraints:
|
2018-10-13 06:44:18 +00:00
|
|
|
|
2018-10-10 21:03:31 +00:00
|
|
|
- ``foo`` matches any version.
|
|
|
|
|
- ``foo<2`` only matches versions before 2.
|
|
|
|
|
- ``foo>=3.1`` matches any version from 3.1 or later.
|
|
|
|
|
- ``foo=1.2.3`` requires that foo must be exactly version 1.2.3.
|
2017-12-10 11:50:39 +00:00
|
|
|
|
2018-10-10 07:39:17 +00:00
|
|
|
The following variables may be set upon return. Two sets of values exist:
|
|
|
|
|
One for the common case (``<XXX> = <prefix>``) and another for the
|
|
|
|
|
information ``pkg-config`` provides when called with the ``--static``
|
|
|
|
|
option (``<XXX> = <prefix>_STATIC``).
|
2018-10-10 21:03:31 +00:00
|
|
|
|
|
|
|
|
``<XXX>_FOUND``
|
|
|
|
|
set to 1 if module(s) exist
|
|
|
|
|
``<XXX>_LIBRARIES``
|
|
|
|
|
only the libraries (without the '-l')
|
|
|
|
|
``<XXX>_LINK_LIBRARIES``
|
|
|
|
|
the libraries and their absolute paths
|
|
|
|
|
``<XXX>_LIBRARY_DIRS``
|
|
|
|
|
the paths of the libraries (without the '-L')
|
|
|
|
|
``<XXX>_LDFLAGS``
|
|
|
|
|
all required linker flags
|
|
|
|
|
``<XXX>_LDFLAGS_OTHER``
|
|
|
|
|
all other linker flags
|
|
|
|
|
``<XXX>_INCLUDE_DIRS``
|
|
|
|
|
the '-I' preprocessor flags (without the '-I')
|
|
|
|
|
``<XXX>_CFLAGS``
|
|
|
|
|
all required cflags
|
|
|
|
|
``<XXX>_CFLAGS_OTHER``
|
|
|
|
|
the other compiler flags
|
2017-12-10 11:50:39 +00:00
|
|
|
|
|
|
|
|
All but ``<XXX>_FOUND`` may be a :ref:`;-list <CMake Language Lists>` if the
|
|
|
|
|
associated variable returned from ``pkg-config`` has multiple values.
|
|
|
|
|
|
|
|
|
|
There are some special variables whose prefix depends on the number of
|
|
|
|
|
``<moduleSpec>`` given. When there is only one ``<moduleSpec>``,
|
|
|
|
|
``<YYY>`` will simply be ``<prefix>``, but if two or more ``<moduleSpec>``
|
2018-10-10 07:39:17 +00:00
|
|
|
items are given, ``<YYY>`` will be ``<prefix>_<moduleName>``.
|
2018-10-10 21:03:31 +00:00
|
|
|
|
|
|
|
|
``<YYY>_VERSION``
|
|
|
|
|
version of the module
|
|
|
|
|
``<YYY>_PREFIX``
|
|
|
|
|
prefix directory of the module
|
|
|
|
|
``<YYY>_INCLUDEDIR``
|
|
|
|
|
include directory of the module
|
|
|
|
|
``<YYY>_LIBDIR``
|
|
|
|
|
lib directory of the module

FindPkgConfig: Extend PKG_CONFIG_PATH using CMake variables (#12926)
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.

This can be set to the path of the pkg-config executable. If not provided,
|
|
|
|
|
it will be set by the module as a result of calling :command:`find_program`
|
|
|
|
|
internally. The ``PKG_CONFIG`` environment variable can be used as a hint.
