如何在C ++文件的Cmake文件上添加Mac OS Framework [英] how to add Mac OS Framework on Cmake file for C++ project
问题描述
我正在尝试将外部库（Vulkan）添加到我的项目中。该库是预先编译的并具有框架。
I am trying to add an external library (Vulkan) to my project. This library is pre-compiled and has a framework.
我的项目树：
- build
- source
- Entry
- main.cpp
- include
- ext
- vulkan
- macos
- include
- lib
- Frameworks
- CMakeLists.txt
在我的CMakeLists.txt中，我尝试添加vulkan库的库，如下所示：
In my CMakeLists.txt, I try to add the lib of my vulkan lib like this:
if(APPLE)
set(vulkan_lib_dir ${CMAKE_SOURCE_DIR}/ext/vulkan/macos/lib)
file(GLOB LIB_VULKAN ${vulkan_lib_dir}/*.dylib )
INCLUDE_DIRECTORIES(${CMAKE_SOURCE_DIR}/ext/vulkan/macos/include)
endif()
然后
TARGET_LINK_LIBRARIES(my_exe ${LIB_VULKAN})
当我在构建目录中使用 cmake .. 然后 make 时，它可以完美运行但是当我运行可执行文件 ./ my_exe
When I use cmake .. and then make on my build directory, it works perfectly but when I run my executable ./my_exe
dyld: Library not loaded: /tmp/macos-sdk-build/shaderc/src/build/libshaderc/libshaderc_shared.1.dylib
Referenced from: /Users/benz/Documents/Dev/build/my_exe/source/Entry/./my_exe
Reason: image not found
我认为我也必须在CMake中设置框架，但是我没有找到使 my_exe 起作用的解决方案。
I think I have to set the framework in my CMake too, but I did not find a solution that made my_exe work.
编辑：这是我的可执行文件otool -L的输出
EDIT : this is the output of otool -L of my executable

推荐答案
您正在链接 ../../../../ ext / vulkan / macos / lib / libshaderc_shared.dylib ，如果已运行 otool -L 毫无疑问，它认为它被称为 / tmp /.../ libshaderc_shared.dylib 这是问题的根本原因（它基本上告诉运行时链接程序从何处获取该库）。
You are linking in ../../../../ext/vulkan/macos/lib/libshaderc_shared.dylib and if you ran otool -L on it you would no doubt see that it thinks it's called /tmp/.../libshaderc_shared.dylib which is the root-cause of your issue (it basically tells the runtime linker where to fetch that library from).
该文件已损坏，您只能修复它通过在其上运行 install_name_tool 对其重命名，使其像其他库一样使用 @rpath 。
That file is broken and you can only fix it by running install_name_tool on it to rename it to use @rpath like the other libraries.
但是您不需要链接所有这些库，因此只需将 CMakeLists.txt 文件更改为仅链接 libvulkan.dylib ：
But you don't need to be linking against all those libraries so simply change the CMakeLists.txt file to only link against libvulkan.dylib:
if(APPLE)
set(LIB_VULKAN ${CMAKE_SOURCE_DIR}/ext/vulkan/macos/lib/libvulkan.dylib)
INCLUDE_DIRECTORIES(${CMAKE_SOURCE_DIR}/ext/vulkan/macos/include)
endif()
