cannot select python version during configure of Paraview 5.8

I have multiple versions of python installed on my Mac via Macports. When running ccmake with Parview 5.8, my selections for:
Python3_LIBRARY_RELEASE
_Python3_EXECUTABLE
_Python3_INCLUDE_DIR
_Python3_LIBRARY_RELEASE
Are all ignored. I am trying to select python-3.6 (/opt/local/bin/python3.6), but python-3.8 is always populated after running configure. It seems like there is a bug in the configure procedures. Any ideas?

I found resolution in 19926:

-DPARAVIEW_USE_PYTHON:BOOL=ON 
-DPython3_FIND_STRATEGY=LOCATION 
-DPython3_ROOT_DIR=/opt/local/Library/Frameworks/Python.framework/Versions/3.6/
