CMake problem with Qt 6.10.0

EduardoQtDev

CMake Error at /home/user/Qt/6.10.0/gcc_64/lib/cmake/Qt6Qml/Qt6QmlMacros.cmake:1273 (add_custom_command):
  Error evaluating generator expression:

    $<TARGET_FILE:::qtpaths>

  No target "::qtpaths"
Call Stack (most recent call first):
  /home/user/Qt/6.10.0/gcc_64/lib/cmake/Qt6Qml/Qt6QmlMacros.cmake:1051:EVAL:1 (_qt_internal_write_deferred_qmlls_build_ini_file)
  CMakeLists.txt:DEFERRED

There is this line n the Cmake file
set(qtpaths $<TARGET_FILE:${QT_CMAKE_EXPORT_NAMESPACE}::qtpaths>)
somehow QT_CMAKE_EXPORT_NAMESPACE is not defined.

Maybe it's because 6.10.0 is still in beta1, i.e. not fully baked?

qtpaths is an executable, not a CMake target.
I must admit, that I never use it. But from the top of my head, you have to write something like this instead:

find_program(QTPATHS_EXEC qtpaths)

I think it's a bug in Qt CMake. Just in case someone wants to open a bug report.

https://bugreports.qt.io/browse/QTBUG-137577 - Known, and already fixed it seems. You'll need to wait for beta2, or build from Git.
