如何正确地将静态库的头文件复制到/usr/include?

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

我正在使用C语言，实际上我正在创建两个非常小的静态库。

My goal is:

我的目标是:

The libraries are compiled and linked into *.a files. [THIS WORKS]
这些库被编译并链接到*。一个文件。(这是)
Then I wish to copy that *.a files into /usr/local/lib [THIS ALSO WORKS]
然后我想复制那个*。一个文件进入/usr/local/lib[这也起作用]
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/include, then I can include them the easy way #include <mylibheader.h>. That's how I understand it now.
就我所知的库(非常少)，它们使用-lnameoflib链接，这是一个编译器标志。好的。我已经准备好了我的CMakeLists。txt和它实际上复制*。一个文件到/usr/local/lib.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/include中，然后我可以将它们包含在简单的方法中，包括。这就是我现在的理解。

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.

我的问题是，如何正确地将头文件复制到/usr/include文件夹和CMAKE?我希望在执行安装时自动复制它们，比如*。一个文件。

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

对于这两个库，我都有一个smiliar CMakeLists.txt:

project(programming-network)

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

INSTALL(TARGETS programming-network
        DESTINATION "lib"
        )

SOLUTION

Thanks to the help of comments, I have found a solution (very easy). Now my CMakeLists looks like this:

由于有了评论的帮助，我找到了一个解决方案(非常简单)。现在我的CMakeLists看起来是这样的:

project(programming-network)

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

INSTALL(TARGETS programming-network
        DESTINATION "lib"
        )
INSTALL(FILES programming-network.h
        DESTINATION "../include"
        )

3 个解决方案

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

最新的cmake版本的更好的方法是使用目标的PUBLIC_HEADER属性。

project(myproject)

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

一些参考:

PUBLIC_HEADER

CMake install command

I don't think your solution is the correct one. /usr/include should be reserved for your vendor to put files in.

我认为你的解决方案不正确。/usr/include应该保留给供应商，以便将文件放入。

The proper thing to do IMO is to install the header in /usr/local/include and then instruct the user to export CPATH="/usr/local/include:${CPATH}".

正确的做法是在/usr/local/include中安装header，然后指示用户导出CPATH="/usr/local/include:${CPATH}"。

It seems /usr/local/lib was search automatically but if you wish to use another dir export LIBRARY_PATH="/usr/local/lib:${LIBRARY_PATH}" works similar for the .a binary (but may or may not work good for shared libraries depending on your os).

看起来/usr/local/lib是自动搜索的，但是如果您想要使用另一个dir导出LIBRARY_PATH="/usr/local/lib:${LIBRARY_PATH}"的工作类似于一个二进制文件(但是根据您的操作系统，可以或可能不适合共享库)。

Optionally, but more cumbersome is to add -I /usr/local/include and -L /usr/local/lib while compiling.

但更麻烦的是在编译时添加-I /usr/local/include和-L /usr/local/lib。

This is a somewhat subjective answer, but it's been working well for me.

这是一个有点主观的回答，但对我来说已经很好了。

#3

In a much better way, will copy all files that match the pattern and will preserve the directory structure.

以一种更好的方式，将复制与模式匹配的所有文件，并保存目录结构。

INSTALL (
    DIRECTORY ${CMAKE_SOURCE_DIR}/include/
    DESTINATION include
    FILES_MATCHING PATTERN "*.h*")
