[Development] Loading moc plugins when running tests in CI system

[Aaron McCarthy]

Hi,

Qt Positioning and Qt Location use moc plugins in various test cases. These 
tests run fine locally with a developer build of Qt but fail when run in the 
CI system. From what it looks like this is because the moc plugins are not 
installed and cannot be loaded, see integration failure in [1].

The moc plugins are built under the top-level tests project which is not 
installed by default. My question is what is the recommended approach to 
ensure that moc plugins are loadable when running tests in the CI system?
