linux - 将 autogen.sh 与 ExternalProject_Add 结合使用

Question

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?

但是我有一个问题，我不能调用CONFIGURE_COMMAND configure，因为我必须调用./autogen.sh来生成configure.ac。我找不到如何让 cmake 运行 ./autogen.sh

Answer 1

来自 documentation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.

您可以在外部项目的配置步骤中指定要执行的几个命令:

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