* [cmake] generalize Python output directory in UseTest macro
this is helpful in case we set up another python output directory (eg PySide2)
* define python output directories to the parent scope
* try with target_include_directories
* define vars on top level
* Update UsePythonTest.cmake
* some cleanup
* more cleanup
* fix uic
* fix path for all platforms
* fix var
A race condition triggered that sometimes the file
output/python/qgis/__init__.py was not created before a python uic
compiler started and therefore the required module could not be
imported.
This leads to errors like
[ 82%] Generating ui_dialogAbout.py
Traceback (most recent call last):
