我不是程序员，我只是想让 pdf4qt 工作，这样我就可以看看它是否是 Debian Buster 的一个不错的 pdf 编辑器。我打开它并尝试配置并得到以下信息：

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.

*** cmake process exited with exit code 1.
有人能用通俗的语言告诉我这是什么意思吗？
谢谢
