CMake Error at CMakeLists.txt:12 (find_package):
  Found package configuration file:
    C:/Users/qt/RTA/Qt_6.5.1/6.5.1/msvc2019_arm64/lib/cmake/Qt6/Qt6Config.cmake
  but it set Qt6_FOUND to FALSE so package "Qt6" is considered to be NOT
  FOUND.  Reason given by package:
  Failed to find required Qt component "PdfWidgets".
  Expected Config file at
  "C:/Users/qt/RTA/Qt_6.5.1/6.5.1/msvc2019_arm64/lib/cmake/Qt6PdfWidgets/Qt6PdfWidgetsConfig.cmake"
  does NOT exist
  
  Configuring with --debug-find-pkg=Qt6PdfWidgets might reveal details why
  the package was not found.
  Configuring with -DQT_DEBUG_FIND_PACKAGE=ON will print the values of some
  of the path variables that find_package uses to try and find the package.
-- Configuring incomplete, errors occurred!
