Why unit test "ext_matrix_clip_space.cpp" is not used?

[Josh Chien]

Hi,

When I am trying to use glm as a git submodule of my project...
When I am managing the glm targets that is created via CMakeList...

I found ext_matrix_clip_space.cpp is just contain a empty main function,
and CMakeList do not use it...

why not remove it?

#include <glm/ext/matrix_relational.hpp>
#include <glm/ext/matrix_clip_space.hpp>
#include <glm/ext/matrix_float4x4.hpp>
#include <glm/ext/vector_relational.hpp>
#include <glm/ext/vector_float4.hpp>
#include <glm/ext/vector_float3.hpp>

int main()
{
	int Error = 0;

	return Error;
}
