This library is like sibling to GLM (https://glm.g-truc.net/0.9.8/index.html) which is already in the repo. It is very common to use both at the same time (for development, they are header only). I think it is good idea to provide both , this way we users will always have compatible libraries. Otherwise I must install the library by myself and in some point in time when you decide to upgrade that one in repo my stuff will crash.

Look like vulkan tools are in solus repository as separate packages
