Hi, In the process of making a cygport file for wxPython 4, I've found that I can make use of the PYTHON3-SITELIB (and similar) variables. However, I don't know what version of Python 3 these point to, seeing as they all have separate folders for this. Unless I'm mistaken, there don't seem to be eg PYTHON36-SITELIB or PYTHON37-SITELIB variables, so I'm not sure how to specify which version of Python 3 I'm building/packaging for. Any ideas? Hamish
