Hi!

I'm trying to build 3.2.0 with Python support. All dependencies are installed, however I have issue with adding Python support.

When running cmake -DUSE_PYTHON=yes ., it does detect Python, but only the latest version installed which is 3.8.2, but the main version I have is python 3.7 and Boost is also built only with python 3.7.

I tired passing -DPYTHON_EXECUTABLE=/usr/bin/python3.7 but that doesn't work:
ledger-1.log

If I remove Python 3.8, then cmake -DUSE_PYTHON=yes . finishes without errors:
ledger-2.log

I'm on Gentoo, the following deps are installed:

• Python 3.6, Python 3.7 (this is the main version that is used by the system and is supported by Boost), Python 3.8,
• GCC 9.3.0
• Cmake 3.16.5
• ledger 3.2.0

Is there another option that could help?
