FindOpenJPEG
--------------
Find OpenJPEG headers and libraries.
Imported Targets
^^^^^^^^^^^^^^^^
``OpenJPEG::OpenJPEG``
The OpenJPEG library, if found.
Result Variables
^^^^^^^^^^^^^^^^
This will define the following variables in your project:
``OpenJPEG_FOUND``
true if (the requested version of) OpenJPEG is available.
``OpenJPEG_VERSION``
the version of OpenJPEG.
``OpenJPEG_LIBRARIES``
the libraries to link against to use OpenJPEG.
``OpenJPEG_INCLUDE_DIRS``
where to find the OpenJPEG headers.
``OpenJPEG_COMPILE_OPTIONS``
this should be passed to target_compile_options(), if the
target is not used for linking
