Building / Installation from source fails, due to a wrong use of pathlib in
python scripts. Luckily, the fix is simple.


STEPS TO REPRODUCE

1. have in python3 pathlib and pathlib2 installed

2. download breeze-icons-5.85.0 tarball

3. follow the usual build instructions:

mkdir build
cd build
cmake \
-DCMAKE_INSTALL_PREFIX=/opt/kf5 
-DCMAKE_PREFIX_PATH=/opt/qt5 \
-DCMAKE_BUILD_TYPE=Release \
-DBUILD_TESTING=OFF \
-Wno-dev ..

4. make install


OBSERVED RESULT

As you can see, pathlib and pathlib2 are installed (for various reasons).
Anyway, changing the python script in question

breeze-icons-5.85.0/generate-24px-versions.py :

"from pathlib import Path"  ->  "from pathlib2 import Path"

fixes this problem (at least for me).
