Linux下CMake简明教程

案例1：option

test.cpp

#include <iostream>
 
int main() {
#ifdef TEST_DEBUG
    std::cout<<"123------------------> Hello,Test"<<std::endl;
#endif
    std::cout << "456 Hello------------> World!" << std::endl;
    return 0;
}

CMakeLists.tx:

cmake_minimum_required(VERSION 3.13)
project(cmaks)
 
set(CMAKE_CXX_STANDARD 14)
 
option(TEST_DEBUG "option for TEST" OFF)
if(TEST_DEBUG)
    add_definitions(-DTEST_DEBUG)
endif()
add_executable(cmaks test.cpp)

run.sh:

#!/bin/sh
rm -rf build
ls
mkdir build 
cd build
cmake -DTEST_DEBUG=OFF ..
# cmake --build ..
make 
./cmaks 

cd ../
rm -rf build
mkdir build 
cd build
cmake -DTEST_DEBUG=ON ..
make 
./cmaks 

执行结果：bash run.sh

案例2：list

cmake_minimum_required(VERSION 2.8)
set(mylist aaa)
list(APPEND mylist bbb ccc 9) #追加
# MESSAGE("${mylist}")
list(LENGTH mylist ll)
#insert with index
list(INSERT mylist 1 xxx 3) #插入指定位置1之后的xxx 3
MESSAGE("${mylist}")  

#移除列表中的元素 
list(REMOVE_ITEM mylist 3)
MESSAGE("${mylist}")

aaa;xxx;3;bbb;ccc;9
aaa;xxx;bbb;ccc;9
