64-bit version of Gpg4win

I would like to explain why I need a 64-bit version of Gpg4win for my project.

shemeshg/gpgme-cmake-example/blob/master/libpgpfactory/CMakeLists.txt

include(FeatureSummary)


if (${CMAKE_SYSTEM_NAME} MATCHES "Darwin")
    set(MACOSX TRUE)
endif()
if(UNIX AND NOT APPLE)
    set(LINUX TRUE)
endif()
if(WIN32 OR MSVC OR MSYS OR MINGW)
    set(WINDOWS TRUE)
endif()

if(UNIX)
    # LibGpgError bug must include_directories on root, but can be linked in subdirectory
    set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} ${CMAKE_CURRENT_SOURCE_DIR}/gpgfactory/cmake)
    find_package(LibGpgError REQUIRED)
    include_directories(${LibGpgError_INCLUDE_DIRS})
    # End LibGpgError

Here are some reasons:

Qt6.6.1, the latest version of the popular cross-platform framework, has dropped support for 32-bit and only supports 64-bit and ARM architectures4.
linking you libraries works only with cmake -G "Visual Studio 17 2022".
I’m unable to wrap your project inside x64 library of mine because setting cmake to SHARE will not link the gnupg x86.

I link your project with

if (WINDOWS)
    # Create an IMPORTED target for the libgpgmepp6-6 DLL
    add_library(libgpgmepp6-6 SHARED IMPORTED)
    # Set the location of the DLL file
    set_target_properties(libgpgmepp6-6 PROPERTIES
    IMPORTED_LOCATION "C:/Program Files (x86)/Gpg4win/bin_64/libgpgmepp6-6.dll"
    )
    # Set the location of the .imp file
    set_target_properties(libgpgmepp6-6 PROPERTIES
    IMPORTED_IMPLIB "C:/Program Files (x86)/Gpg4win/lib/libgpgme.imp"
    )
    # Set the include directories for the IMPORTED target
    set_target_properties(libgpgmepp6-6 PROPERTIES
    INTERFACE_INCLUDE_DIRECTORIES "C:/Program Files (x86)/Gpg4win/include"
    )
