在CMake项目中指定项目依赖项

本文介绍了在CMake项目中指定项目依赖项的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我刚开始在C项目中使用CMake进行构建.

I have just started using CMake for my builds on a C project.

我的项目目录结构如下:

My project dir structure looks like this:

MainProject module1/ src/ include/ CMakeLists.txt module1/ src/ include/ CMakeLists.txt .... moduleN/ src/ include/ CMakeLists.txt

目前，我正在正确地构建模块，但是，现在，我希望能够指定模块间的依赖关系，以便在创建模块时，将重新构建其所有依赖的模块(如果已更改).

At the moment, I am building my modules correctly, However, I now want to be able to specify intermodule dependencies so that when I make a module, all of its dependent modules are rebuilt (if changed).

我的CMakeLists.txt文件通常如下所示:

My CMakeLists.txt file typically looks like this:

CMAKE_MINIMUM_REQUIRED(VERSION 2.8) PROJECT( basetypes ) FIND_PACKAGE( Threads ) SET(CMAKE_C_FLAGS ${CMAKE_C_FLAGS} "-pthread") ADD_DEFINITIONS(-DE4C_THREADSAFE ) INCLUDE_DIRECTORIES ("include/") SET( basetypes_SRCS src/btypes_1.c src/btypes_2.c src/btypes_3.c src/btypes_4.c src/btypes_5.c src/vfuncs.c src/btypes_6.c src/btypes_7.c src/btypes_8.c src/btypes_8.c src/e4c.c ) ADD_LIBRARY(basetypes SHARED ${basetypes_SRCS}) set(CMAKE_LIBRARY_OUTPUT_DIRECTORY "bin/")

如何修改此类CMakeLists文件以指定其他从属项目?

How can I modify such a CMakeLists file to specify other dependent project(s)?

推荐答案

尝试 target_link_libraries 命令.但是，它需要知道模块名称，所以我建议您编写一个全局CMakeLists文件，其中包含 add_subdirectory 命令.

Try target_link_libraries command. However, it need to know module names, so I've suggest you to write one globale CMakeLists file, that include modules by add_subdirectory command.
