This library implements 2 types: quat (quanterion) and dquat (dual-quaternion). Both types can be templated with different number types, or one of the typedefs (quatf_t, quatd_t, dquatf_t, dquatd_t) can be used.
Will attempt to find GLM headers. If <glm/gtc/constants.hpp>, <glm/mat4x4.hpp>, <glm/vec4.hpp> and <glm/vec3.hpp> are available, cql will generate functions for conversion to and from GLM vectors and matrices
