我尝试在CMakeLists.txt中设置ExternalProject_Add,

为此,我发现了这个问题：

What is the correct usage of CMake EXTERNALPROJECT_ADD with a Git repository?

但我有一个问题,我不能调用CONFIGURE_COMMAND配置,因为我必须调用./autogen.sh来生成configure.ac.
我没有找到如何让cmake运行./autogen.sh

解决方法:

从documentation开始关于ExternalProject：

Any builtin step that specifies a <step>_COMMAND cmd... or custom step that specifies a COMMAND cmd... may specify additional command lines using the form COMMAND cmd.... At build time the commands will be executed in order and aborted if any one fails.

您可以指定在外部项目的配置步骤中执行的几个命令：

ExternalProject_Add(<some_project>
   ...
   CONFIGURE_COMMAND ./autogen.sh COMMAND ./configure
)
