Consider the following situation: There are CMake tests in qttools/tests/auto/cmake that configure and build CMake test projects, essentially as external projects. One of those test projects does find_package(Qt6 COMPONENTS LinguistTools). This call fails in a prefix build, because Qt6LinguistToolsConfig.cmake is not installed yet. It merely exists in qttools-build/lib/cmake/Qt6LinguistTools. We must adjust CMAKE_PREFIX_PATH to be able to find Qt6LinguistTools. We also must adjust QT_ADDITIONAL_PACKAGES_PREFIX_PATH to be able to find the LinguistTools component of the Qt6 package. Use the prefixes setup from the support for building examples as external projects and use it for CMake test projects as well.
