Question

我正在编写一个跨平台程序，希望将其打包在Windows上。我通过在构建目录中放置三个DLL（Qt5Core，Qt5Widgets，Qt5Gui）来运行它，然后制作了一个tarball，并用Windows盒子将其提供给其他人，但是它不能在他的Windows盒子上运行。我搜索了一种获取所需其他信息的方法，并找到了内森·奥斯曼（Nathan Osman）关于windeployqt的帖子，因此我将windeployqt.cmake复制到cmake / Modules目录，但不知道如何使用它。是否可以使用CPack制作一个程序包（即使只是一个tarball），该程序包具有在未安装编译器或Qt的Windows机器上运行程序所需的一切？

这是CMakeLists.txt文件，其中删除了一些（希望是不相关的）内容：

include(CTest)

Answer 1

如果${CMAKE_SOURCE_DIR}/cmake/Modules/目录中已经有文件Windeployqt.cmake，则可以这样使用它：

install(TARGETS perfecttin-gui 
    DESTINATION "${INSTALL_BIN_PATH}"
)

if(WIN32)
    include(Windeployqt)
    windeployqt(nitroshare-cli ${INSTALL_BIN_PATH})
endif()

Here是完整的示例。

我在这方面花了很长时间，虽然我从 this answer 那里借了很多东西，但是它缺少导致 Warning: Cannot find GCC installation directory. g++.exe must be in the path. 的必要环境设置。

Qt 有以下关于使用 windeployqt.exe 的文档

The tool can be found in QTDIR/bin/windeployqt. It needs to be run within the build environment in order to function correctly.
When using Qt Installer, the script QTDIR/bin/qtenv2.bat should be used to set it up.

基本上归结为使用正确的环境设置将 windeployqt.exe 作为自定义命令运行。

# Retrieve the absolute path to qmake and then use that path to find
# the windeployqt executable
get_target_property(QMAKE_EXE Qt6::qmake IMPORTED_LOCATION)
get_filename_component(QT_BIN_DIR"${QMAKE_EXE }" DIRECTORY)

find_program(WINDEPLOYQT_ENV_SETUP qtenv2.bat HINTS "${QT_BIN_DIR}")
find_program(WINDEPLOYQT_EXECUTABLE windeployqt HINTS "${QT_BIN_DIR}")

# Run windeployqt immediately after build
add_custom_command(TARGET perfecttin-gui
    POST_BUILD
    COMMAND "${WINDEPLOYQT_ENV_SETUP}" && "${WINDEPLOYQT_EXECUTABLE}" \"$<TARGET_FILE:perfectin-gui>\"
)

如何在Windows上打包使用CMake构建的Qt程序？
