Petrus Hyvönen commented on PYLUCENE-62:
----------------------------------------
Did an attempt to use the add_jvm_dll_directory_to_path() approach, seems to
work fine in the test environments I have. I took the order of picking up java
from: JCC_JDK, JAVA_HOME and then registry. As it is now, the python3.8+ on
windows does not care about the PATH at all. It could be added to scrape around
in PATH as well, but hesitant to have too many places for it? Also added
windows.py to the modules to be embedded to avoid the need of also installing
JCC on the target package.
