Go to make build easier.

Build document

  • CMakeLists.txt
    • like Makefile
  • add_executable(<name> source1 [source2 …])
    • Adds an executable target called <name> to be built from the source files listed in the command invocation.
    • The <name> corresponds to the logical target name and must be globally unique within a project.

      * c++11 support
        - add_compile_options() will add the options to gcc and g++
        - set(CMAKE_CXX_FLAGS) works for g++ only

if(CMAKE_COMPILER_IS_GNUCXX)
# add_compile_options(-std=c++11)
set(CMAKE_CXX_FLAGS “${CMAKE_CXX_FLAGS} -std=c++11”)
message(STATUS “optional:-std=c++11”)

endif(CMAKE_COMPILER_IS_GNUCXX)

# single source file
add_executable(stest single_list.cpp)

# multiple source files
add_executable(main
    create1.cpp
    create2.cpp
    create3.cpp
)

Build a single file

  • a single source file is going to be built into an executable binary

    cmake_minimum_required(VERSION 2.8)

    add_executable(stest single_list.cpp)

Build multiple files in sub directory

  • serveral files in different sub direcotries, build them all in the root directory, and also could build each in a sub directory.
