#.rst:
# 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.
