Cannot use Qt Quick Application with Qt 5 and CMake

1. Configure the Qt VS Tools to use Qt 5.
   I used Qt 5.15.16 x64 from the official Online Installer.
2. Create a new CMake-based Qt Quick Application project using the wizard.
   CMake generation fails:

   Severity	Code	Description	Project	File	Line	Suppression State	Details
   Error		CMake Error at QtQuickApplication10/qt.cmake:14 (add_executable):
     Cannot find source file:
   
       qml.qrc
   
     Tried extensions .c .C .c++ .cc .cpp .cxx .cu .mpp .m .M .mm .ixx .cppm
     .ccm .cxxm .c++m .h .hh .h++ .hm .hpp .hxx .in .txx .f .F .for .f77 .f90
     .f95 .f03 .hip .ispc		D:\tmp\msvs\QtQuickApplication10\QtQuickApplication10/qt.cmake	14		
   

   That source file is not there, indeed.

With Qt 6.6.1, creating and building such a project works fine.

Found when extending Squish test tst_new_project_file_creation.
