Qt Creatorの使い方

Qt Creatorの使い方

私はプログラマーではありません。単にpdf4qtを動作させ、Debian Busterに適したPDFエディタであることを確認したいだけです。私はそれを開き、設定を試して、次のようになりました。

    Running "/usr/local/bin/cmake /home/Rob/Downloads/PDF4QT-1.3.1 '-GCodeBlocks - Ninja' -DCMAKE_CXX_COMPILER:STRING=/usr/bin/g++ -DCMAKE_C_COMPILER:STRING=/usr/bin/gcc -DCMAKE_PREFIX_PATH:STRING=/usr -DQT_QMAKE_EXECUTABLE:STRING=/usr/lib/qt5/bin/qmake" in /tmp/QtCreator-fjypKO/qtc-cmake-tKrZfijV.

CMake Error at CMakeLists.txt:46 (find_package):
  By not providing "FindQt6.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Qt6", but
  CMake did not find one.

  Could not find a package configuration file provided by "Qt6" with any of
  the following names:

    Qt6Config.cmake
    qt6-config.cmake

  Add the installation prefix of "Qt6" to CMAKE_PREFIX_PATH or set "Qt6_DIR"
  to a directory containing one of the above files.  If "Qt6" provides a
  separate development package or SDK, be sure it has been installed.


-- Configuring incomplete, errors occurred!

素人の観点から、これが何を意味するのか教えてもらえますか?

ありがとう
