使用 autogen.sh 和 ExternalProject_Add

using autogen.sh with ExternalProject_Add

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

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.

您可以指定几个命令在外部项目的配置步骤执行:

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