qgroundcontrol 编译的问题

用的 qt 5.4.1 和 vs 2013 64位编译系统
[1] - Project MESSAGE: Qt version 5.4.1
[2] - Project MESSAGE: Windows build
[3] - Project MESSAGE: Release flavor
[4] - Project MESSAGE: BASEDIR E:/qgroundcontrol-Stable_V2.3 DESTDIR E:/qgroundcontrol-Stable_V2.3/release TARGET qgroundcontrol
[5] - Project ERROR: MAVLink folder does not exist at 'libs/mavlink/include/mavlink/v1.0'! Run 'git submodule init && git submodule update' on the command line.

--- (Import): Error(s): 5
--- (qmake) : Exit Code: 3

mavlink文件夹里什么都没有
就是libs/mavlink/include/mavlink/v1.0里面

把 mp里面的mavlink文件 dll复制过去，还是不行，有没有编译成功的指点一下
