QtFtp and QtHttp builds fail because of missing CMake tests

The builds for QtFtp and QtHttp fail because the variable CMAKE_MODULE_TESTS is not set.

Project ERROR: Missing CMake tests.

I fixed it locally by adding

CMAKE_MODULE_TESTS=-

(which just skips the check)
or

CONFIG -= create_cmake

(which disables the generation of the CMake files)
to the project file.
