GLM is a header only library. Hence, there is nothing to build to use it. To use GLM, a programmer only has to include <glm/glm.hpp> in his program. This include provides all the GLSL features implemented by
GLM.
Core GLM features can be included using individual headers to allow
faster user program compilations.

1.2. Faster program compilation {#faster-program-compilation .HeadingB}
-------------------------------
### 1.2. Faster program compilation
GLM is a header only library that makes a heavy usage of C++ templates.
This design may significantly increase the compile time for files that
use GLM. Hence, it is important to limit GLM inclusion to header and
source files that actually use it. Likewise, GLM extensions should be
included only in program sources using them.

included only in program sources using them.
To further help compilation time, GLM 0.9.5 introduced
<glm/fwd.hpp> that provides forward declarations of GLM types.
