笔记 cmake 使用

1.添加路径

add_subdirectory("replay")

2.添加执行程序

add_executable(replay "replay.cc")

3.设置项目文件路径

set_target_properties(replay PROPERTIES FOLDER replay)

4.设置依赖库

target_link_litraries(replay sc2api)

5.编译库

file(GLOB sources_replay "replay/*.cpp" "replay/.cc" "replay/*.h")

add_library(replay sources_replay)

5.添加依赖库头文件路径

link_directories(${BOOST_ROOT}/include)

6.查找依赖库

SET(BOOST_COMPONENTS)
LIST(APPEND BOOST_COMPONENTS thread
                             date_time
                             system
                             filesystem
                             program_options
                             signals
                             serialization
                             chrono
                             unit_test_framework
                             context
                             locale
                             coroutine)
FIND_PACKAGE(Boost 1.60 REQUIRED COMPONENTS ${BOOST_COMPONENTS})

7.设置编译版本

add_compile_options(-std=c++11)

8.设置库文件编译属性

set_target_properties(${target} PROPERTIES LINKER_LANGUAGE CXX)

9.cmake 输出错误信息，

message(FATAL_ERROR " please set MYSQLCPP_ROOT_DIR")

10.find_library

find_library(mysql_libs mysqlcppconn ${MYSQLCPP_ROOT_DIR})

11.设置编译语言

SET_TARGET_PROPERTIES(libbbbb PROPERTIES LINKER_LANGUAGE C)

12.引入*.cmake

SET(CMAKE_MODULE_PATH ${CMAKE_CURRENT_SOURCE_DIR}/cmake)
include(xxxxxx)

14.添加宏参数 

add_definitions(-DBITPRIM_CURRENCY_BCH)

15.自定义宏

macro(add_design_path path)
    file(GLOB souce_file "mode/${path}/*.hpp" "mode/${path}/*.cpp")
    add_executable("${path}" ${souce_file})
    target_include_directories(${path} PUBLIC "mode/${path}")
endmacro()

16.foreach

set(design_path
        factory)

foreach(path ${design_path})
    add_design_path(${path})
endforeach()

17.获取执行命令

execute_process(
        COMMAND	git log -1 --format=%H
        WORKING_DIRECTORY "${CMAKE_CURRENT_SOURCE_DIR}"
        OUTPUT_VARIABLE GIT_VERSION
)

string (REGEX REPLACE "[\n\t\r]" "" GIT_VERSION  ${GIT_VERSION})
