The
INTERFACE_LINK_LIBRARIES
forpango_opengl
contains the CMake targetsOpenGL::EGL
andepoxy::epoxy
, which are interpreted as libraries in external projects, unless their packages are imported viafind_package
orfind_dependency
. For the OpenGL targets, where the "Find*" macros are available via the original package, this can be fixed by addingfind_dependency
to thePangolinConfig.cmake
. However, for epoxy such "Find*" package is not easily available and would need to be manually added by each external project. Hence, we revert back to the old-style CMake includes and libraries, such that theINTERFACE_LINK_LIBRARIES
will contain the path to the shared object for epoxy.Fixes #936.
