include_directories(${Qt5Test_INCLUDE_DIRS})

or 

include(${Qt5Declarative_USE_FILE})

You add the line I just added above in between.

The use file is a convenience that is relatively common in cmake modules that 
adds includes and definitions etc, but the more direct way is also possible.

If the test is in a different directory with its own CMakeLists file it's also 
easier.

So I don't think the Qt5Config.cmake presents any new issues.
