FindLibDRM
----------
Find libdrm headers and libraries.
Imported Targets
^^^^^^^^^^^^^^^^
``LibDRM::LibDRM``
The libdrm library, if found.
Result Variables
^^^^^^^^^^^^^^^^
This will define the following variables in your project:
``LibDRM_FOUND``
true if (the requested version of) libdrm is available.
``LibDRM_VERSION``
the libdrm version.
``LibDRM_LIBRARIES``
the libraries to link against to use libdrm.
``LibDRM_INCLUDE_DIRS``
where to find the libdrm headers.
``LibDRM_COMPILE_OPTIONS``
this should be passed to target_compile_options(), if the
target is not used for linking
