Thank you for raising this, building Python and Fortran at the same time is something we have yet to test, and points to something I need to fix in the CMake files. I will look at the details.
The build system has been updated further, to make python stable. The PYTHON cmake option has now been removed. It has been replaces with PYTHON_BUILD_SETUP, which is intended to be called from scikit-build-core, when you call "pip install". The recommended way to install highspy is via "pip install ." from the root dir, or from PyPi. We have now pushed a pre-release version 1.7.1.dev0, which you are very welcome to check out. If you run into any further problems, please open a new issue.
Note, that setting PYTHON_BUILD_SETUP will disable building the standard C++ libraries, which Fortran will depend on. Please build Fortran and Python separately.
