FindLibinput
------------

Find libinput headers and library.

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 version of libinput.
``Libinput_LIBRARIES``
  the libraries 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
  target is not used for linking

#]=======================================================================]

# Use pkg-config to get the directories and then use these values
# in the FIND_PATH() and FIND_LIBRARY() calls
