When using gli in a project that also uses glm and adds preprocessor definitions on the command line, gli triggers compiler warnings such as: gli/./core/levels.inl:2: warning: "GLM_ENABLE_EXPERIMENTAL" redefined This commit fixes this by only defining the preprocessor symbols if they are not already present. This helps maintain warning-free downstream code.
