Hi there, please bear with me as this is my first post.
I would like to discuss this particular comment in the FindOpenGL.cmake file
For EGL targets the client must rely on GLVND support on the user’s system. Linking should use the
OpenGL::OpenGL OpenGL::EGLtargets. Using GLES* libraries is theoretically possible in place of
OpenGL::OpenGL, but this module does not currently support that; contributions welcome.

I want to help make this contribution, but I want to make sure I’m not missing anything. I have an environment which seems to exercise this missing feature: a Yocto-based embedded Linux which uses GLES. I added a quick hack which makes the FindOpenGL module look for libEGLv2.so instead of libOpenGL.so, and it seems to work. So I thought the fix would just be something like
if (NOT OPENGL_opengl_LIBRARY) # look again for EGLv1/v2
This seems too easy to be true, so I’m sure I’m missing something. Could someone more knowledgeable in this area let me know if this is a viable fix?
Thanks a lot.
