CMAKE-如何正确地将静态库的头文件复制到/ usr / include？ [英] CMAKE - How to properly copy static library's header file into /usr/include?

问题描述

我正在使用C进行CMAKE使用，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。 [此
   工作]


2. 然后我希望将* .a文件复制到/ usr / local / lib [这也应工作]


3. 据我所知，关于库（很少），它们是使用 -lnameoflib 链接的，这是一个编译器标志。好。我已经准备好了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，我还需要将其头文件复制到 / usr / local / include 中，然后可以通过简单的方法将它们包括在 #include< mylibheader.h> 。这就是我现在的理解。

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-将头文件复制到/ usr / include文件夹的正确方法是什么？ CMAKE？我希望在执行 make install 时自动复制它们，例如* .a文件。

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.

这两个库我都有一个比较简单的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版本的更好方法是：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
)
