In 724e833ea2, I was a little too aggressive in enabling these flags.
Many don’t work in gcc, and we should probably avoid settings them
widely. This makes those flags optional on isclang
The examples fail with an opengl related issue:
Undefined symbols for architecture x86_64:
"SimpleOpenGL3App::SimpleOpenGL3App(char const*, int, int, bool)", referenced from:
_main in main_opengl_single_example.o
"_useShadowMap", referenced from:
GL_ShapeDrawer::drawScene(btDiscreteDynamicsWorld const*, bool, int) in GL_ShapeDrawer.o
ld: symbol(s) not found for architecture x86_64
And the tests need an extra dependencly, possibley related to
https://github.com/bulletphysics/bullet3/issues/819
ld: library not found for -lBussIK
