cmake/ninja: Not working after installing wheel via pip

`cmake` and `ninja` as C++ build tools can be installed as python packages by using `pip`.
BUT: If I do that I seem to get a broken package (or some file permissions are not correct: maybe executable permissions are missing).

HOW TO REPEAT:

```sh
$ pip install ninja
…
Using … ninja-1.10.2.3-py2.py3-none-macosx_10_9_universal2.macosx_10_9_x86_64.macosx_11_0_arm64.macosx_11_0_universal2.whl
…

$ ninja —version
ninja: command not found

$ python -m ninja —version
$HOME/Library/lib/python3.9/site-packages/ninja/data/bin/ninja: command not found

# ALTERNATIVE: export PATH=“$PATH:$HOME/Library/bin“
# USE: ninja —version
```
