opm-simulators/python/simulators/CMakeLists.txt
Markus Blatt 02666a6677 Use CMake's find_file to find install.py for Python installation.
This seems to be a more stable approach as it does not produce
```
/usr/bin/python3.9: can't open file
'/home/mblatt/src/dune/opm-2.9/opm-common//install.py': [Errno 2] No such file or directory
```
for rebuilds after failed attempts.
