I'm facing a similar issue. I'm trying to narrow down the optimization flags used to determine what is causing my issues. I have yet to find other flags than the ones accepted for GCC_OPTIMIZATION_LEVEL.

What platform is this on? This is on iOS. I managed to get past the error for Foundation.framework by unincluding it from our cmake build by removing a -framework Foundation flag. I am facing the same error but for OpenGLES now, so I assume it has something to do with duplicate use of Frameworks. So far, attempting to remove OpenGLES and OpenGL frameworks has been unsuccessful. Thanks for the response!

Apologies, I forgot to include the whole error. This line was above the "Library not loaded:" line: dyld[439]: dyld cache '(null)' not loaded: syscall to map cache into shared region failed.
