cmake使用ExternalProject_Add编译第三方库?报错

include(ExternalProject)
ExternalProject_Add(libuv
        #URL http://libuv.org/dist/v0.10.27/libuv-v0.10.27.tar.gz
        #SOURCE_DIR ${PROJECT_SOURCE_DIR}/third/libuv
        SOURCE_DIR /home/action/workspace/cmake/2/third/libuv
        BUILD_COMMAND ${MAKE}
        BUILD_IN_SOURCE 1

)

具体的内容是这样，然后每次运行的结果都报错：

[ 10%] Performing configure step for 'libuv'
CMake Error: The source directory "/home/action/workspace/cmake/2/third/libuv" does not appear to contain CMakeLists.txt.
Specify --help for usage, or press the help button on the CMake GUI.
make[2]: *** [libuv-prefix/src/libuv-stamp/libuv-configure] Error 1
make[1]: *** [CMakeFiles/libuv.dir/all] Error 2
make: *** [all] Error 2

每次都是提示这个，难道不支持没有CMakeLists.txt的项目么，我从stackoverflow搜索到ExternalProject_Add的相关例子，全都是这样的。不管是相对路径，还是绝对路径，全是这样，，，已经崩溃了
