FindLCMS2
---------
Find LCMS2 headers and libraries.
Imported Targets
^^^^^^^^^^^^^^^^
``LCMS2::LCMS2``
The LCMS2 library, if found.
Result Variables
^^^^^^^^^^^^^^^^
This will define the following variables in your project:
``LCMS2_FOUND``
true if (the requested version of) LCMS2 is available.
``LCMS2_VERSION``
the version of LCMS2.
``LCMS2_LIBRARIES``
the libraries to link against to use LCMS2.
``LCMS2_INCLUDE_DIRS``
where to find the LCMS2 headers.
``LCMS2_COMPILE_OPTIONS``
this should be passed to target_compile_options(), if the
target is not used for linking
