同理，find_package(Qt5) 则是会去找名为 Qt5Config.cmake 的文件。 • 这些形如 包名 + Config.cmake 的文件，我称之为包配置文件。 • Qt5Config.cmake 是你安装 Qt5 时，随 libQt5Core.so 等实际的库文件，一起装到你的系统中去的。以我的 Arch Linux 系统为例： • 包配置文件位于 /usr/lib/cmake/Qt5/Qt5Config 系统，find_package(Qt5 REQUIRED) 会依次搜索： • /usr/lib/cmake/Qt5/Qt5Config.cmake • /usr/lib/x86_64-linux-gnu/cmake/Qt5/Qt5Config.cmake • /usr/share/cmake/Qt5/Qt5Config.cmake • /usr/lib/Qt5/Qt5Config.cmake /usr/lib/x86_64-linux-gnu/Qt5/Qt5Config.cmake • /usr/share/Qt5/Qt5Config.cmake • /usr/Qt5/lib/cmake/Qt5/Qt5Config.cmake • /usr/Qt5/lib/x86_64-linux-gnu/cmake/Qt5/Qt5Config.cmake • /usr/Qt5/share/cmake/Qt5/Qt5Config

finder，尽量用系统自带的，可以保证用的是系统自带库的那个配置。 ## find_package(Qt5 REQUIRED) 出错了 ## find_package(Qt5 REQUIRED) target_link_libraries(main PUBLIC Qt5::Widgets Qt5::Gui) CMake Error at CMakeLists.txt:6 (find_package): /usr/lib64/cmake/Qt5/Qt5Config.cmake but it set Qt5_FOUND to FALSE so package "Qt5" is considered to be NOT FOUND.

that did not do things the "right way", and it wasn't clear what that was to me at first. Qt5 improved its integration with CMake quite significantly – moving from using the qmake command to find common prefix. There is a better way, and it makes many of these things simpler again: find_package(Qt5 COMPONENTS Core Widgets REQUIRED) This is not only more compact, which is always nice, but it means
