一， 目录结构
├── cmake-examples.conf
├── CMakeLists.txt
├── include
│ └── installing
│ └── Hello.h
└── src
├── Hello.cpp
└── main.cpp
* link:CMakeLists.txt[] - Contains the CMake commands you wish to run
* link:cmake-examples.conf[] - An example configuration file
* link:include/installing/Hello.h[] - The header file to include
* link:src/Hello.cpp[] - A source file to compile
* link:src/main.cpp[] - The source file with main
二，cmake脚本
cmake_minimum_required(VERSION 3.5)
project(cmake_examples_install)
# 根据源码创建共享库
add_library(cmake_examples_inst SHARED src/Hello.cpp)
#添加头文件目录
target_include_directories(cmake_examples_inst
PUBLIC
${PROJECT_SOURCE_DIR}/include
)
# 创建可执行程序
add_executable(cmake_examples_inst_bin
src/main.cpp
)
# 链接动态库
target_link_libraries( cmake_examples_inst_bin
PRIVATE
cmake_examples_inst
)
# 安装bin文件到指定目录
install (TARGETS cmake_examples_inst_bin DESTINATION bin)
# 安装库文件到指定目录，在windows上可能有问题！！！
# install (TARGETS cmake_examples_inst LIBRARY DESTINATION lib)
# 安装头文件到指定目录
install(DIRECTORY ${PROJECT_SOURCE_DIR}/include/ DESTINATION include)
# 安装配置文件到指定目录
install (FILES cmake-examples.conf DESTINATION etc)
三，扩展分析
cmake提供安装文件的功能，通过执行make install将会安装编译后的可执行程序，配置文件，库文件等。
安装目录的目录前缀由变量CMAKE_INSTALL_PREFIX设置。在执行cmake程序的时候可以通过执行
类似下面这样的命令来设置CMAKE_INSTALL_PREFIX。
cmake .. -DCMAKE_INSTALL_PREFIX=/install/location
install(TARGETS cmake_example LIBRARY DESTINATION bin) 展开为
install(TARGETS cmake_example LIBRARY DESTINATION ${CMAKE_INSTALL_PREFIX}/bin)
其他以此类推。
