使用cmake创建共享库 [英] create a shared library with cmake

问题描述

我写了一个库，我用自编的Makefile编译，但现在我想切换到cmake。树看起来像这样（我删除了所有不相关的文件）：

I have written a library that I used to compile using a self-written Makefile, but now I want to switch to cmake. The tree looks like this (I removed all the irrelevant files):

.
├── include
│   ├── animation.h
│   ├── buffers.h
│   ├── ...
│   ├── vertex.h
│   └── world.h
└── src
    ├── animation.cpp
    ├── buffers.cpp
    ├── ...
    ├── vertex.cpp
    └── world.cpp

所以我想做的只是将源代码编译成共享库，然后用头文件安装它。

So what I am trying to do is just to compile the source into a shared library and then install it with the header files.

大多数例子，我发现编译可执行文件一些共享库，但从不只是一个简单的共享库。
如果有人能告诉我一个使用cmake的非常简单的库，我可以用这个例子。

Most examples that I have found compile executables with some shared libraries but never just a plain shared library. It would also be helpful if someone could just tell me a very simple library that uses cmake, so I can use this as an example.

推荐答案

这个最小的CMakeLists.txt文件编译一个简单的共享库：

This minimal CMakeLists.txt file compiles a simple shared library:

cmake_minimum_required(VERSION 2.8)

project (test)
set(CMAKE_BUILD_TYPE Release)

include_directories(${CMAKE_CURRENT_SOURCE_DIR}/include)
add_library(test SHARED src/test.cpp)

但是，我没有经验使用CMake将文件复制到不同的目的地。带有COPY / INSTALL签名的文件命令看起来可能很有用。

However, I have no experience copying files to a different destination with CMake. The file command with the COPY/INSTALL signature looks like it might be useful.
