Scikit-build 0.17.3

[jcfr]

A small release related to PYTHON_LIBRARY handling changes in 0.17.2; scikit-build 0.17.3 returns an empty string from get_python_library if no Python library is present (like on manylinux), where 0.17.2 returned None, and previous versions returned a non-existent path. Note that adding REQUIRED to find_package(PythonLibs will fail, but it is incorrect (you must not link to libPython.so) and was really just injecting a non-existent path before.

Bug fixes

• Keep get_python_library return type string if python lib non-existing for now in revert: keep return type string if python lib non-existing for now #959.
• Avoid 'not found' warning if libs are not found by FindPythonExtensions in fix: avoid 'not found' warning if libs are not found #960.
• FindNumPy should not call FindPythonLibs in fix: FindNumPy should not call FindPythonLibs #958.
