This commit adds the function `glm_perspective_lh_zo`, modelled on the implementation of glm_perspective, but amended to provide a left-hand coordinate system expected by DirectX, Metal and Vulkan (per the GLM project's `glm/detail/setup.hpp`). It uses a clip-space of zero-to-one. The function is tested against a longhand version of the algorithm it seeks to implement as well as against the output of the GLM project's `glm::perspectiveLH_ZO` function. This commit adds a new subdirectory `test/glm_cmp` which contains a basic CMake file and `main.cpp`. An interested user should link or copy or clone the GLM project into this directory. The `main` function can be used to print the reference data used so others can verify behaviour in the future, or add new literal reference values.
