no, i don't think there's any way to do that cause those classes are
also used in the core so the core needs to be recompiled and use the
same setting as the project if that setting changes.
the only solution i think would be to have anything that uses those
classes also templated but it seems to much
but the idea is that that would be changed by users just that you would
change it for all your projects instead of for per project.
also even if you have that setting set to glm most things will still
work, it's mostly things like:
vector<ofVec3f> vec = mesh.getVertices()
or anything that returns a vector of vec that would need to be fixed
when using glm as the default.
