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.

FindLibinput
|
|
------------
|
|
|
|
.. versionadded:: 3.14
|
|
|
|
Finds the libinput library which handles input devices in Wayland compositors
|
|
and provides a generic X.Org input driver:
|
|
|
|
.. code-block:: cmake
|
|
|
|
find_package(Libinput [<version>] [...])
|
|
|
|
Imported Targets
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
This module provides the following :ref:`Imported Targets`:
|
|
|
|
``Libinput::Libinput``
|
|
Target encapsulating the libinput library usage requirements, available only
|
|
if library is found.
|
|
|
|
Result Variables
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
This module defines the following variables:
|
|
|
|
``Libinput_FOUND``
|
|
Boolean indicating whether the (requested version of) libinput library is
|
|
found.
|
|
``Libinput_VERSION``
|
|
The version of the libinput found.
|
|
``Libinput_LIBRARIES``
|
|
The libraries to link against to use the libinput library.
|
|
``Libinput_INCLUDE_DIRS``
|
|
The include directories containing headers needed to use the libinput library.
|
|
``Libinput_COMPILE_OPTIONS``
|
|
Compile options needed to use the libinput library. These can be passed to
|
|
the :command:`target_compile_options` command, when not using the
|
|
``Libinput::Libinput`` imported target.
|
|
|
|
Examples
|
|
^^^^^^^^
|
|
|
|
Finding the libinput library and linking it to a project target:
|
|
|
|
.. code-block:: cmake
|
|
|
|
find_package(Libinput)
|
|
target_link_libraries(project_target PRIVATE Libinput::Libinput)
|
|
#]=======================================================================]
|
|
|
|
|
|
# Use pkg-config to get the directories and then use these values
|
|
# in the FIND_PATH() and FIND_LIBRARY() calls
|
|
find_package(PkgConfig QUIET)
