I am including the glm library in my Xcode project and want to suppress this warning: /opt/extlibs/macosx/include/glm/./ext/../gtc/bitfield.inl:343:15: warning: Although the value stored to 'x' is used in the enclosing expression, the value is never actually read from 'x' [deadcode.DeadStores] uint16 REG2(x >>= 1); ^ ~ Is there a way to do that via a #pragma or a #define or something else in the Build Settings?
