Cmake process makes user's OS dirty

[MNikora]

Cmake process is not only preparing project to building, but installing extra packages.

Reproduction Steps

1. cd sdl_core && mkdir build && cd build
2. cmake ..

Expected Behavior

-- Build files have been written to: /home/developer/sdl/sdl_core/build

Observed Behavior

The directory '/home/developer/.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.
The directory '/home/developer/.cache/pip' or its parent directory is not owned by the current user and caching wheels has been disabled. check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.
