CMAKE - Remove example build from src/CMakeLists.txt (#469)

* CMAKE - Remove example build from src/CMakeLists.txt
For some reason it was building examples every time even when not
necessary...
* CMAKE - Format
* Fix drm_example broken PRIu32
* CMAKE - Do NOT create lib64 when building examples
* CMAKE - Examples should only install C and CMake files
