cmake语法基础

cmake use

• 主目录下CMakeLists

cmake_minimum_required(VERSION 3.9.5)
project(exchange)

message(${PROJECT_SOURCE_DIR})

set(CMAKE_C_COMPILER "gcc")
set(CMAKE_CXX_COMPILER "g++")

aux_source_directory(. DIR_MAIN)
include_directories(${PROJECT_SOURCE_DIR}/inc)
link_directories(${PROJECT_SOURCE_DIR}/lib)
# add_subdirectory(inc) # 在上面生成lib或者创建子文件夹，这个文件夹用来生成lib库

add_executable(exchange
        ${DIR_MAIN})

target_link_libraries(
        exchange
        test

• inc目录下用于生成lib库的CMakeLists

cmake_minimum_required(VERSION 3.9.5)

# generate lib
SET(LIBRARY_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/lib)
aux_source_directory(. DIR_INC)
add_library(hellolib ${DIR_INC})
