CMake 基本操作基本头添加

CMake 基本操作以及头添加

CMake Github 参考学习网站

基本结构 需要CMakeList.txt 和相关的代码文件

cmake_minimum_required(VERSION 2.6)
project (hello_cmake)
add_executable(${PROJECT_NAME} main.cpp)

常用CMake命令	描述
cmake_minimun_required	设置所需最低版本
project	设置工程名
add_executable	规定编译后的可执行文件名
set	设置变量
target_include_directories	目标的相关头文件目录
message	打印信息
add_library	添加源文件并设置库

常用CMake 参数	描述
CMAKE_SOURCE_DIR	顶层CMakeList.txt所在路径
CMAKE_ROOT	CMake 安装路径
PROJECT_NAME	project()命令所设置的名称
CMAKE_PROJECT_NAME	顶层CMake Project名称（首次设置）
PROJECT_SOURCE_DIR	工程CMakeList.txt所在路径
PROJECT_BINARY_DIR	编译所在路径（执行的路径cmake）
CMAKE_CURRENT_BINARY_DIR	当前工程编译所在路径
CMAKE_CURRENT_SOURCE_DIR	当前工程所在路径

# Set the minimum version of CMake that can be used
# To find the cmake version run
# $ cmake --version
cmake_minimum_required(VERSION 3.5)

# Set the project name
project (hello_headers)

# Create a sources variable with a link to all cpp files to compile
set(SOURCES
    src/Hello.cpp
    src/main.cpp
)

# Add an executable with the above sources
add_executable(hello_headers ${SOURCES})

# Set the directories that should be included in the build command for this target
# when running g++ these will be included as -I/directory/path/
target_include_directories(hello_headers
    PRIVATE
        ${PROJECT_SOURCE_DIR}/include
)
