How do I build DLLs from vcpkg into CPacked installer?

[SamuelMarks]

The cpack executable is the CMake packaging program. It generates installers and source packages in a variety of formats.

I'm using cpack -G WIX -C Debug on my SamuelMarks/cmake-example-with-vcpkg. Which produces a nice installer, but it doesn't copy/install zlibd1.dll (from vcpkg).

How is this meant to work?

Hey!
Copying the dependencies automatically is still experimental, but you can try setting X_VCPKG_APPLOCAL_DEPS_INSTALL to ON.
That should copy dependencies into the install target directory for executables.

Add to CMakeLists.txt:

    # X_VCPKG_APPLOCAL_DEPS_INSTALL depends on CMake policy CMP0087 and requires CMake 3.14
    if(POLICY CMP0087)
        cmake_policy(SET CMP0087 NEW)
    endif()

    set(X_VCPKG_APPLOCAL_DEPS_INSTALL ON)

Thanks I added that but it didn't copy the DLLs over. Is it CPack compatible?

CPack relies on CMake install comands and additional staging directories. I have no ideas if this works with vcpkg's staging, install, and applocal install. For cross-platform deployment of DLLs without vcpkg, I normally use CMake's BundleUtilities. IIUC parts of these functions now even became part of the file command (https://cmake.org/cmake/help/latest/command/file.html#get-runtime-dependencies).

@dg0yt Yes I tried that approach https://gitlab.kitware.com/cmake/cmake/-/issues/22431 https://gitlab.kitware.com/cmake/cmake/-/issues/22006

Did you run cmake install command?

CPack is running cmake install.

it doesn't copy/install zlibd1.dll (from vcpkg).

• Note that the wrapper for zlib is missing, [zlib] Add cmake wrapper #18914, which may cause some strange effects.
• If not using a multi-config generator, don't let CMAKE_BUILD_TYPE be unset, or there will be strange effects.
