SOFTWARE/OS VERSIONS
Windows: 11
KDE Plasma Version: 6.3.0
KDE Frameworks Version: 6.10.0
Qt Version: 6.8.2
ADDITIONAL INFORMATION
This is my suspcion:

endfunction() < ---- #1 Once we get here, Qt6Core_FOUND is set to 1, but
this line clears it
if(BUILD_QT6)
build_Qt6()
endif()
function(build_colors_and_cursors)
# While it is technically not 100% correct to use versionless
# KDEInstallDirs while (maybe) building for both Qt versions,
# it doesn't really matter at the end, because colors and cursors
# only use ICONDIR and DATADIR which both do not depend on the version
include(KDEInstallDirs)
add_subdirectory(colors)
add_subdirectory(cursors) < --- #3 This looks for Qt6:Core again, with an
unset `Qt6Core_FOUND` which in turn gets to that point where
Qt6EntryPointPrivateConfig.cmake is called again.
