CMake命令总结

1.单个文件的编译

cmake_minimum_required(VERSION 2.8)
add_executable(Main main.cpp)

编译命令

cmake .
make

2. 单目录多源文件编译

cmake_minimum_required(VERSION 2.8)
add_executable(Main
  main.cpp
  mod_func1.cpp
  mod_func2.cpp
)

3. 多目录程序的编译

项目名/
  main.cpp
  mod1.hpp
  mod1/
    func1.cpp
    func2.cpp
  mod2.hpp
  mod2/
    func1.cpp
    func2.cpp

方法1 根目录编写CMakeLists.txt

cmake_minimum_required(VERSION 2.8)
add_executable(Main
  main.cpp
  mod1/func1.cpp
  mod1/func2.cpp
  mod2/func1.cpp
  mod2/func2.cpp
)

方法2：每个目录编写CMakeLists.txt

#CMakeLists.txt
cmake_minimum_required(VERSION 2.8)
add_subdirectory(mod1) 
add_subdirectory(mod2) 
add_executable(Main main.cpp)
target_link_libraries(Main Mod1 Mod2) 

#mod1/CMakeLists.txt
cmake_minimum_required(VERSION 2.8)
add_library(Mod1 STATIC
  func1.cpp
  func2.cpp
)
