用cmake链接库 [英] Link library with cmake

问题描述

我在电脑上安装了库 bcm2835 。要在c中编译程序，我必须输入：

I installed the library bcm2835 on my pc. To compile a program in c I must type:

gcc -o my_program my_program.c -l rt -l bcm2835 

现在，我必须使用 cmake 。我从来没有使用过。
我必须在 cmakelists.txt的底部添加什么？

Now I must compile another program that use the same libraries with cmake. I have never used this. What must I add to the bottom of "cmakelists.txt"?

我尝试过：

TARGET_LINK_LIBRARIES(my_program rt)  
TARGET_LINK_LIBRARIES(my_program bcm2835)

但这不起作用。

推荐答案

cmake_minimum_required (VERSION 2.6)
project( my_program )

find_library( rt_lib rt OTHER_PARAMETERS_THAT_YOU_REQUIRE_SEE_DOCUMENTATION_LINK )
find_library( bcm2835_lib bcm2835 OTHER_PARAMETERS_THAT_YOU_REQUIRE_SEE_DOCUMENTATION_LINK )

include_directories( LIST_OF_REQUIRED_INCLUDE_DIRECTORIES_SEE_DOCUMENTATION_LINK ) 

add_executable( my_program my_program.c )
target_link_libraries( my_program rt_lib bcm2835_lib )

此处
和此处和此处是一些示例，由于CMake具有好的文档，您应该阅读有关命令的更多信息 。

Here and here and here are some examples and since CMake has good documentation you should read more about the commands here.

并且cmakelists.txt文件应命名为CMakeLists.txt

And cmakelists.txt files should be named CMakeLists.txt
