Can't build Qt6 from sources: invalid synax of QML modules

[r3d9477]

Hi everyone, I'm trying to build Qt6 installed via Conan

[requires]
boost/1.85.0
gtest/1.14.0
qt/6.7.3

[options]
qt/*:shared=True
qt/*:qtshadertools=True
qt/*:qtdeclarative=True

[generators]
CMakeDeps
CMakeToolchain

[layout]
cmake_layout

but got strange exception:

Does anybody know what was happened?
Thanks

I was also seeing the same strange error and struggling to work out where it came from:

qmldir file not found at "some/path"

turned out it was a call to qt_import_qml_plugins.

Not sure what this means in the context of this conan build, though.
