Add test for correct installation

[Framstag]

We should make sure that installation via cmake or meson is working and equal.

Idea:
Make both install in local installation directories (non-root). Write some bash script(or similar) that offers some functions for testing for availability of file at the given path.

Create the script by testing for strategic files at the right places. Such files could be:

• Library files
• Binaries
• Certain header files (representative for all header files)

Call the script on each installation. Make sure script and build fail on error.

Further note: (we could use a similar approach for checking a distribution archive).
