Yup. You can find the packages under Pi Menu > Preferences > Add/Remove Software. Doing a search there will eventually bring up the needed modules.

I am still curious as how one builds the modules separately though.

Thanks again!

So is qtdatavis3d's Abstract3DRenderer just not compatible with desktop OpenGL versions higher than 2.1? If so that is pretty limiting!

I've written a short test to verify that QOpenGLContext::versionFunctions() returns nullptr for QOpenGLFunctions_2_1, but returns an object for QOpenGLFunctions_4_5_Core on my Ubuntu machine (which has OpenGL 4.5 installed).
