* For BCMHOST build, use brcmEGL / brcmGLESv2 libraries, and don't look at
Mesa includes (so libraspberrypi-dev and libgles*-mesa-dev can coexist).
* If overridden via -DGLES=On, don't present vendor includes to build to
make absolutely sure that the Mesa includes are used.
Fixes stretch vendor library building & generic Mesa GLES compatibility.
CMake is much more versatile, providing build support on multiple
platforms to generate Makefiles. This should serve as a starting point
for CMake builds.
Please note the /CMake/* scripts are actually ripped from the ORGE3D
repositories, but they seem to be in the Public Domain. Thanks!
