CMake install(IMPORTED_RUNTIME_ARTIFACTS ?

Perdrix

I added this to my CMakeLists.txt on Linux to get the Qt6 libraries copied to my install directory

install(IMPORTED_RUNTIME_ARTIFACTS
Qt6::Core
Qt6::Gui
Qt6::Widgets
Qt6::Network
Qt6::DBus
Qt6::OpenGLWidgets
)
That indeed copies the libraries into the install directory and modifies the application rpath:

-- Install configuration: "Debug"

Unfortunately it didn't copy (at least) libicui18n.so.73 which is also in the Qt libs directory, and probably some others as well, so I get:

error while loading shared libraries: libicui18n.so.73: cannot open shared object file

How should I do this please? I'm not planning to use linuxdeployqt ATM.

Thanks

How about just using cp either directly or in a script ?

If found a recent addition to Qt that does pretty much what I want (though it adds more Qt libraries than are necessary - I think it just copies them all :( ). It is qt_generate_deploy_app_script

Here's the complete code from my CMakeLists.txt file showing the both the non-Linux and the Linux path:

if(NOT LINUX)
    set (deploy_tool_options_arg "")
    if(APPLE)
        set(deploy_tool_options_arg "${deploy_tool_options_arg} --hardened-runtime")
    elseif(WIN32)
        set(deploy_tool_options_arg "${deploy_tool_options_arg} --pdb")
    endif()

    # Generate a deployment script to be executed at install time
    # App bundles on macOS have an .app suffix
    if(APPLE)
        set(executable_path "$<TARGET_FILE_NAME:DeepSkyStacker>.app")
    else()
        message ("Target filename:"  $<TARGET_FILE_NAME:DeepSkyStacker>)
        set(executable_path "${CMAKE_INSTALL_BINDIR}/$<TARGET_FILE_NAME:DeepSkyStacker>")
    endif()
    message ("executable_path: " ${executable_path})
    message ("deploy tools options arg: " ${deploy_tool_options_arg})
     qt_generate_deploy_script(
         TARGET DeepSkyStacker
         OUTPUT_SCRIPT deploy_script
         CONTENT "
     qt_deploy_runtime_dependencies(
         EXECUTABLE \"${executable_path}\"
         DEPLOY_TOOL_OPTIONS ${deploy_tool_options_arg}
     )"
     )
else()
qt_generate_deploy_app_script(
    TARGET ${PROJECT_NAME}
    OUTPUT_SCRIPT deploy_script
    DEPLOY_TOOL_OPTIONS ${deploy_tool_options_arg}
)
endif()
install (SCRIPT ${deploy_script})

install(TARGETS ${PROJECT_NAME})

Be warned if you are using the Visual Studio Linux workload: It invokes CMake on Linux with

-DCMAKE_SYSTEM_NAME:STRING=“Linux”

which is a big "no-no". It results in CMAKE_CROSSCOMPILING being set to TRUE which results in qt_generate_deploy_app_script refusing to play.
