CMAKE - 如何将静态库的头文件正确复制到/usr/include 中? [英] CMAKE - How to properly copy static library's header file into /usr/include?

问题描述

我开始使用 C 来使用 CMAKE，实际上我正在创建两个非常小的静态库.

I'm getting into CMAKE usage with C and actually I'm creating two very small static libraries.

我的目标是:

1. 库被编译并链接到 *.a 文件中.[这作品]
2. 然后我希望将 *.a 文件复制到/usr/local/lib [这也有效]
3. 就我对库的了解(很少)，它们使用 -lnameoflib 链接，这是一个编译器标志.行.我已经准备好了我的 CMakeLists.txt，它实际上将 *.a 文件复制到 /usr/local/lib 中.但是，为了能够在程序中使用它们，我还需要将它们的头文件复制到 /usr/local/include 中，然后我可以通过简单的方式包含它们 #include #include <mylibheader.h>.我现在就是这么理解的.

1. The libraries are compiled and linked into *.a files. [THIS WORKS]
2. Then I wish to copy that *.a files into /usr/local/lib [THIS ALSO WORKS]
3. As far as I know about libraries (very little), they are linked using -lnameoflib, which is a compiler flag. OK. I have prepared my CMakeLists.txt and it actually copies *.a files into /usr/local/lib. However, to be able to use them in a program, I also need to copy their header files into /usr/local/include, then I can include them the easy way #include <mylibheader.h>. That's how I understand it now.

我的问题是 - 使用 CMAKE 将头文件复制到/usr/include 文件夹的正确方法是什么?我希望它在执行 make install 时自动复制它们，就像 *.a 文件一样.

And my question is - how is the proper way of copying header files into /usr/include folder with CMAKE? I would like it to copy them automatically when make install is executed, like *.a files are.

对于这两个库，我都有一个类似的 CMakeLists.txt:

For both of the libraries I have a smiliar CMakeLists.txt:

project(programming-network)

add_library(programming-network STATIC
    send_string.c
    recv_line.c
    )

INSTALL(TARGETS programming-network
        DESTINATION "lib"
        )

推荐答案

最新的 cmake 版本更好的方法是使用目标的 PUBLIC_HEADER 属性.

A better way for newest cmake version is to use target's PUBLIC_HEADER properties.

project(myproject)

add_library(mylib some.c another.c)
set_target_properties(mylib PROPERTIES PUBLIC_HEADER "some.h;another.h")
INSTALL(TARGETS mylib 
        LIBRARY DESTINATION some/libpath
        PUBLIC_HEADER DESTINATION some/includepath
)

一些参考:
