Thank you!
I think for linux you set up Kha framework somewhere (which is self-contained except c++ compiler) and run in the repo dir something like
# compile the runtime
path_to/Kha/make linux --build --compile
# substitute windows runtime
mkdir Exporter/platforms/windows
mv build/linux/MousePSD Exporter/platforms/windows/MousePSD.exe
# install exporter dependencies
pip3 install -r Exporter/requirements.txt
# run exporter
python3 ./Exporter/mouse.py
