FindEpoxy
---------
Find the Epoxy (*libepoxy*) headers and library.
Imported Targets
^^^^^^^^^^^^^^^^
``Epoxy::Epoxy``
The Epoxy library, if found.
Result Variables
^^^^^^^^^^^^^^^^
This will define the following variables in your project:
``Epoxy_FOUND``
true if (the requested version of) Epoxy is available.
``Epoxy_VERSION``
the version of Epoxy; only defined when a ``pkg-config`` module for
Epoxy is available.
``Epoxy_LIBRARIES``
the libraries to link against to use Epoxy.
``Epoxy_INCLUDE_DIRS``
where to find the Epoxy headers.
``Epoxy_COMPILE_OPTIONS``
this should be passed to target_compile_options(), if the
target is not used for linking
