Standalone test projects have the following condition in the
beginning of their project:
if(NOT QT_BUILD_STANDALONE_TESTS AND NOT QT_BUILDING_QT)
find_package(Qt6BuildInternals COMPONENT STANDALONE_TEST)
endif()
When configuring the project the first time, QT_BUILDING_QT is not
set, find_package is called, configuration succeeds.
But because standalone projects implicitly include QtSetup.cmake,
that file sets the QT_BUILDING_QT cache var to true, and upon test
reconfiguration, cmake errors out with:
Unknown CMake command "qt_internal_add_test"
or similar.
This happens because QT_BUILDING_QT is true on the second
reconfiguration and the find_package mentioned above is not executed
anymore, leading to unknown internal command errors.
Set a new QT_INTERNAL_IS_STANDALONE_TEST variable when we detect
a standalone test and check for its value in QtSetup so we don't
set QT_BUILDING_QT to TRUE anymore.
Adjust a few code locations where QT_BUILDING_QT being false might
trigger different behavior for standalone tests.
