[gtkada] Configure doesn't find openGL

[Pascal]

Hello,

That's a while I have built GTKAda with OpenGL support on MacOS.

I did it with X11 backend:
$ CPPFLAGS=-I$instxada/include LDFLAGS=-L$instxada/lib ./configure CC='gcc -g -O0' --prefix=$instxada --enable-build=Debug --with-GL=GL --with-GL-prefix=/usr/X11 --disable-shared
(instxada=your installation directory)

If you want native MacOS backend, try to add in GTKAda GPR file:
for Linker_Options use ("-g", "-bind_at_load", "-framework", "/GLUT", "-framework", "/OpenGL", "-lm", "-Wl,-no_pie");

Keep us informed.

HTH, Pascal.
