Findepoxy
---------
Try to find libepoxy on a Unix system.
This will define the following variables:
``epoxy_FOUND``
True if (the requested version of) libepoxy is available
``epoxy_VERSION``
The version of libepoxy
``epoxy_LIBRARIES``
This should be passed to target_link_libraries() if the target is not
used for linking
``epoxy_INCLUDE_DIRS``
This should be passed to target_include_directories() if the target is not
used for linking
``epoxy_DEFINITIONS``
This should be passed to target_compile_options() if the target is not
used for linking
``epoxy_HAS_GLX``
True if GLX support is available
If ``epoxy_FOUND`` is TRUE, it will also define the following imported target:
``epoxy::epoxy``
The epoxy library
In general we recommend using the imported target, as it is easier to use.
Bear in mind, however, that if the target is in the link interface of an
exported library, it must be made available by the package config file.
