Cannot "Mark Directory as" anything but a python namespace package in CLion 2020.3

Question

I am working with CLion and when loading a project from a valid CMakeLists file I get the warning that none of the files belong to any project target. This is annoying and I found a solution here that seems to work for most people.

In CLion, header only library: file "does not belong to any project target, code insight features might not work properly"

However when I try and mark an include directory as part of the project there is not an option. The only options is to mark it has a python namespace package. Googling for this issue didn't seem to turn anything up. Does anyone know why that option would not be there?

You can remove the CLion configuration in the containing folder then reopen the project.

rm -rf .idea

It did work for me.
