@philnik777 @mordante @EricWF  I'd like someone to take a look at this. IMO this is an important improvement to the way we conceptually run the test suite: we run it on the result of installing the library, which means we test exactly what we ship.

However, this adds some verbosity to the build due to some CMake limitations and I'd like someone else to try it out and let me know what they think.
