I suppose one thing you could try is forcing a different CMake version:
# Show currently installed verion
(mfix-23.3.1)C:> conda list cmake
# packages in environment at C:\Users\cgw\mambaforge\envs\mfix-23.3.1:
#
# Name Version Build Channel
cmake 3.27.6 hf0feee3_0 conda-forge
# Shows all available versions
(mfix-23.3.1)C:> conda search -c conda-forge cmake
# Name Version Build Channel
cmake 3.5.0 0 conda-forge
...
cmake 3.27.5 hf0feee3_0 conda-forge
cmake 3.27.6 hf0feee3_0 conda-forge
MFiX requires CMake version at least 3.16 (or maybe 3.24?) but you could try installing some different CMake versions and see if it helps:
(mfix-23.3.1)C:> conda install -c conda-forge cmake=3.27.5
Keep trying different versions, working backward until you find one that works (produces output when you run cmake --version).
If this works for you please let us know!
