A user wouldn't normally have it installed unless something required it or they turned on testing. I apologise, I forgot that qtbase is typically kept together (we split it into its various components) so yes the issue this addresses is definitely more distro-specific than I originally thought. However, since we now know that anything marked with ecm_mark_as_test can be turned off, one could argue that it's technically incorrect to search for a package that will not be used.

Would you consider having just 'if (BUILD_TESTING) find_package(Qt5Test) endif()' in the root?
