FindLibInput
------------

Find libinput headers and libraries.

Imported Targets
^^^^^^^^^^^^^^^^

``LibInput::LibInput``
  The libinput library, if found.

Result Variables
^^^^^^^^^^^^^^^^

This will define the following variables in your project:

``LibInput_FOUND``
  true if (the requested version of) libinput is available.
``LibInput_VERSION``
  the libinput version.
``LibInput_LIBRARIES``
  the library to link against to use libinput.
``LibInput_INCLUDE_DIRS``
  where to find the libinput headers.
``LibInput_COMPILE_OPTIONS``
  this should be passed to target_compile_options(), if the imported
  target is not used for linking.
