Configuration and compile documentation improvements. * Improve the stable and testing build version option logic. * Use CMake FindPythonInterp to configure the Python interpreter. * Use Python interpreter to determine the system Python module install path if not already defined on the command line. * Add header symbol checks for asinh(), acosh(), and atanh(). * Add test source to check for isinf() which can be defined as a C++template. * Replace conditional compile on windows systems for aXXXh() with CMake configuration tests. * A few minor MSVC compile fixes. * Fix incorrect python environment string in fixswigimports.py * Create a separate document for KiCad CMake build options. * Create a separate how to compile KiCad on Windows document.
