Executing `make clean` in the `build` folder deletes the `README` files from the modules folders.
This is probably because the README is an output of a `cmake-make` command. What would be the best option to skip this removing?
I found:
- https://stackoverflow.com/questions/6259372/cmake-preventing-make-clean-from...
Which indicates adding:
``` SET_DIRECTORY_PROPERTIES(PROPERTIES CLEAN_NO_CUSTOM 1) ```
In the CMakeLists.txt inside the module folders. But maybe it is another place where it can be done once for all modules, or another option...
