-# 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.
