使用CPack在Mac上打包系统守护进程

Question

我试图在Mac上创建一个系统范围的服务，使用CMake进行构建，使用CPack生成包。存储库相当大，所以我创建了一个较小的版本来测试它。结果发现，我不知道如何将有绝对路径的东西打包成目的地。

这是CMake代码：

install(PROGRAMS ${CMAKE_BINARY_DIR}/hello
        DESTINATION "/var/local/hello"
        COMPONENT TS
      )

install(PROGRAMS com.hello.world.plist
        DESTINATION "/Library/LaunchDaemons/"
        COMPONENT TS
      )

这是cpack的输出

mac-mini-2:build melanoholly$ cpack ..
CPack: Create package using productbuild
CPack: Install projects
CPack: - Run preinstall target for: testingPack
CPack: - Install project: testingPack
CMake Error at /Users/salvobit/sandbox/cpack-example-mac-daemon/build/cmake_install.cmake:44 (file):
  file cannot create directory: /var/local/hello.  Maybe need administrative
  privileges.


CMake Error at /Users/salvobit/sandbox/cpack-example-mac-daemon/build/cmake_install.cmake:56 (file):
  file INSTALL cannot copy file
  "/Users/salvobit/sandbox/cpack-example-mac-daemon/com.hello.world.plist" to
  "/Library/LaunchDaemons/com.hello.world.plist".


CPack Error: Error when generating package: testingPack

如果我以根用户身份运行cpack，则生成的包是空的。

谁能告诉我怎么解决这个问题吗？

我使用3.13.0-rc2版本的CMake。

解决这个问题的关键是将CMAKE_INSTALL_PREFIX指定为

set(CMAKE_INSTALL_PREFIX "/")

当您这样做时，您可以在/var/中安装路径

install(PROGRAMS <binary>
        DESTINATION "../var")
