Clion一个项目多个main()函数

C语言项目，在CMakeLists.txt里添加

cmake_minimum_required(VERSION 3.17)
 
get_filename_component(ProjectId ${CMAKE_CURRENT_SOURCE_DIR} NAME)
string(REPLACE " " "_" ProjectId ${ProjectId})
project(${ProjectId} C)
 
set(CMAKE_C_STANDARD 11)
 
file(GLOB files "${CMAKE_CURRENT_SOURCE_DIR}/*.c")
foreach(file ${files})
    get_filename_component(name ${file} NAME)
    add_executable(${name} ${file})
endforeach()

C++语言项目，在CMakeLists.txt里添加

cmake_minimum_required(VERSION 3.19)
 
get_filename_component(ProjectId ${CMAKE_CURRENT_SOURCE_DIR} NAME)
string(REPLACE " " "_" ProjectId ${ProjectId})
project(algorithms) #项目名称
 
set(CMAKE_CXX_STANDARD 98) #使用c++98
 
file(GLOB files "${CMAKE_CURRENT_SOURCE_DIR}/*.cpp")
foreach(file ${files})
    get_filename_component(name ${file} NAME)
    add_executable(${name} ${file})
endforeach()

原来CMakeLists.txt里面有其他代码，全部替换即可，替换完记得Reload下项目

每次新建.c或.cpp文件也要Reload项目
