如何使用cmake脚本从命令行中选择用于编译C ++代码的xcode版本

Question

In the MAC there are two xcode APP: one is xcode4 and the other is xcode5. When I compile the C++ project with cmake, it will invoke xcode 5 directly rather than xcode 4, and I was wondering whether there is a way to call xcode 4 directly when I invoke cmake scripts from command line. Thanks.

EDIT:

Final solution is

sudo xcode-select --switch Path/to/xcode4

After that setting, it will work. I try to set the enviroment varialbe DEVELOPER_DIR, although I can clearly see that the directed path is xcode4, when invoking cmake scripts it still call xcode5.

Currently used Xcode version can be received by executing:

xcode-select --print-path

You can change it by modifying environment variable DEVELOPER_DIR . From documentation :

   DEVELOPER_DIR
      Overrides the active developer directory. When DEVELOPER_DIR is set,
      its  value  will  be  used instead of the system-wide
      active developer directory.
