dynamic resource file location

[mPorst]

Hello Daniel,

I wanted to try out the testbed but ran into a small problem regarding resource files (shaders and .obj files) not being found on windows with vscode.
I'd like to implement a dynamic search of these resources using std::filesystem.
It is a little more work than I anticipated (meshes needs to be adapted in all scenes). I can work with copying the folder on my end, but if you're interested in this as a feature I would go through the work and create a merge request.

Unfortunately compilers handle the exact paths where they put their compiled executables differently.
