wrong python dist-packages location

[mlg556]

I do not know if this is specific to my system (maybe it's broken), but sudo make install installs the python module to:
/usr/local/lib/python3/dist-packages/grdab, which is not in my python packages path (this results in a ModuleNotFoundError: No module named 'grdab'):

➜  ~ python3 -m site
sys.path = [
    '/usr/lib/python39.zip',
    '/usr/lib/python3.9',
    '/usr/lib/python3.9/lib-dynload',
    '/usr/local/lib/python3.9/dist-packages',
    '/usr/lib/python3/dist-packages',
    '/usr/lib/python3.9/dist-packages',
]

I think this is because in cmake, ${CMAKE_INSTALL_PREFIX} defaults to /usr/local, so the cmake_install.cmake files have the line:

file(INSTALL DESTINATION "${CMAKE_INSTALL_PREFIX}/lib/python3/dist-packages/grdab" TYPE FILE FILES

again, this sounds like a problem on my system (Kubuntu 21.10 x86_64.), but maybe other people are having similar problems ?

I have the same problem. (ubuntu 20.04.3)

I had the same issue in MacOS (Monterey 12.1). Adding the Python Dir Flag -DGR_PYTHON_DIR= to cmake ../ solved this issue for me.
So in my case with a macports install of Python
cmake ../ -DGR_PYTHON_DIR=/opt/local/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages
