This is the error returned when I run cmake -B build -G Ninja:

Installing in /usr/local. Run /home/vehementham/haruna/build/prefix.sh to set the environment for haruna.
CMake Warning at /usr/share/ECM/kde-modules/KDEGitCommitHooks.cmake:84 (message):

CMake Error at CMakeLists.txt:43 (find_package):
  Could not find a package configuration file provided by "QT" with any of
  the following names:

    Qt6Config.cmake
    qt6-config.cmake
    Qt5Config.cmake
    qt5-config.cmake

  Add the installation prefix of "QT" to CMAKE_PREFIX_PATH or set "QT_DIR" to
  a directory containing one of the above files.  If "QT" provides a separate
  development package or SDK, be sure it has been installed.
