FindGBM
-------
Find libgbm headers and libraries.
Imported Targets
^^^^^^^^^^^^^^^^
``GBM::GBM``
The libgbm library, if found.
Result Variables
^^^^^^^^^^^^^^^^
This will define the following variables in your project:
``GBM_FOUND``
true if (the requested version of) libgbm is available.
``GBM_VERSION``
the libgbm version.
``GBM_LIBRARIES``
the library to link against to use libgbm.
``GBM_INCLUDE_DIRS``
where to find the libgbm headers.
``GBM_COMPILE_OPTIONS``
this should be passed to target_compile_options(), if the imported
target is not used for linking.
