If egl.pc sets at least two macros as the i.MX Vivante driver does, e.g.:
| Cflags: -I${includedir} -DLINUX -DWL_EGL_PLATFORM
then we get the following error during configuration:
| -- Performing Test HAVE_OPENGL_EGL
| CMake Error: Parse error in command line argument: WL_EGL_PLATFORM
| Should be: VAR:type=value
If one changes to add a value to the macro, e.g.
| Cflags: -I${includedir} -DLINUX=1 -DWL_EGL_PLATFORM=1
then cmake does not error out but the macro is not passed to the
C compiler.
CMAKE_REQUIRED_FLAGS is the wrong variable to pass the CFLAGS in,
CMAKE_REQUIRED_DEFINITIONS should be used.
