Describe the bug
CMake fails to complete successfully because the script is looking for a directory called "build" within the "SDL2-2.28.5" directory.\

Expected behavior
The script should run without errors created by the script itself.

To Reproduce
Run the kivy dependency installation script as per the instructions found at https://kivy.org/doc/stable/gettingstarted/installation.html
