wxWidgets 3.1.5+ on Linux will compile with the Wayland EGL canvas as the backend instead of the X11 backend. This requires a version of GLEW compiled with the proper EGL defines and a different header/code for certain parts that are X11 GLEW specific. This introduces an in-tree version of GLEW that will be built with the GLEW_EGL flag then statically linked into the KiCad executables when EGL support is needed.
