linux – 如何使用CPack以特定方式为QT应用程序打包依赖项？

我正在尝试打包它以便分发.我遇到了查找依赖项并将其打包并以惯用方式执行此操作的问题(IOW：没有硬编码的DLL路径或包含我的源代码库中的DLL)

对于Windows端口,我正在使用MinGW并进行如下编译：

mingw64-cmake -G "Unix Makefiles" .. -DCMAKE_INSTALL_PREFIX=../install -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE=/usr/share/mingw/toolchain-mingw64.cmake
make && ctest && make install && cpack -G "TGZ" && cpack -G "NSIS64"

我已将其设置为生成tar.gz文件和NSIS安装程序.目前没有特别的理由让NSIS而不是Wix.这只是为了解决问题.

它编译Windows可执行文件,但它不包括运行该程序所需的DLL.就是这些：

Libgcc_s_seh-1.dll
Qt5Core.dll
Qt5Gui.dll

在我的计算机上快速查找显示这些DLL存在于此处：

/usr/x86_64-w64-mingw32/sys-root/mingw/bin/Qt5Widgets.dll
/usr/x86_64-w64-mingw32/sys-root/mingw/bin/libgcc_s_seh-1.dll
...

有没有办法自动让CPack挖掘DLL并将它们包含在安装程序中？

这是我的CMakeLists.txt文件：

cmake_minimum_required(VERSION 2.8.11)

project(myapp)

enable_testing()

set(CMAKE_INCLUDE_CURRENT_DIR ON)
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTOUIC ON)
set(CMAKE_AUTORCC ON)
set(CMAKE_POSITION_INDEPENDENT_CODE ON)

find_package(Qt5Core REQUIRED)
find_package(Qt5Gui REQUIRED)
find_package(Qt5Widgets REQUIRED)

add_executable(myapp WIN32 main.cpp mainwindow.cpp resources.qrc)

target_link_libraries(myapp Qt5::Widgets)
target_link_libraries(myapp Qt5::Core)
target_link_libraries(myapp Qt5::Gui)

INSTALL(TARGETS myapp
        BUNDLE DESTINATION .
        RUNTIME DESTINATION bin
        LIBRARY DESTINATION lib
        ARCHIVE DESTINATION lib
        )

INSTALL(FILES ${CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS} DESTINATION bin COMPONENT Libraries)     

IF(CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS)
    INSTALL(PROGRAMS ${CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS} DESTINATION bin COMPONENT System)
ENDIF(CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS)

INCLUDE(CPack)

我四处寻找一些帮助.我遇到的最好的事情是

但它看起来并不那么惯用.如果我们仔细观察CMakeLists.txt文件,它将获得特定于机器的硬编码路径,这些路径将来肯定会发生变化：

IF(    WIN32 AND ${ARCH_32BIT})

    SET(QT_INSTALLED_PATH "C:/QtMSVCX86/Qt5.5.0/5.5/msvc2013" )

ELSEIF(WIN32 AND ${ARCH_64BIT})

    SET(QT_INSTALLED_PATH "C:/QtMSVCX64/Qt5.5.0/5.5/msvc2013_64" )

ELSEIF(UNIX  AND NOT MINGW AND ${ARCH_32BIT})

    SET(QT_INSTALLED_PATH "/opt/Qt5.5.0/5.5/gcc/" )

ELSEIF(UNIX  AND NOT MINGW AND ${ARCH_64BIT})

    SET(QT_INSTALLED_PATH "/opt/Qt5.5.0/5.5/gcc_64/" )

ENDIF()

SET(CMAKE_AUTOMOC ON)
SET(CMAKE_AUTOUIC ON)
SET(CMAKE_AUTORCC ON)

FIND_PACKAGE(Qt5Widgets PATHS  ${QT_INSTALLED_PATH} NO_DEFAULT_PATH)
FIND_PACKAGE(Qt5Qml     PATHS  ${QT_INSTALLED_PATH} NO_DEFAULT_PATH)
