在

1、

2、

的基础上，建立include和src目录：

每个目录的内容如下：

文件内容与：

内容相同，对

CMakeLists.txt进行重构：

cmake_minimum_required ( VERSION 3.17 ) project ( multifiles CXX ) set ( PRJ_SRC_LIST ) set ( PRJ_HEADER_LIST ) set ( PRJ_LIBRARIES ) set ( PRJ_INCLUDE_DIRS ) set ( prj_inc_dir ${CMAKE_CURRENT_SOURCE_DIR}/include ) set ( prj_src_dir ${CMAKE_CURRENT_SOURCE_DIR}/src ) file ( GLOB root_header_files "${prj_inc_dir}/*.h" ) file ( GLOB root_src_files "${prj_src_dir}/*.cpp" ) message ( STATUS " root_header_files = ${root_header_files}") message ( STATUS " root_src_files = ${root_src_files}") list ( APPEND PRJ_HEADER_LIST ${root_header_files} ) list ( APPEND PRJ_SRC_LIST ${root_src_files} ) list ( APPEND PRJ_INCLUDE_DIRS ${prj_inc_dir} ) add_executable ( ${PROJECT_NAME} ${PRJ_SRC_LIST} ${PRJ_HEADER_LIST} ) target_include_directories ( ${PROJECT_NAME} PRIVATE ${PRJ_INCLUDE_DIRS} target_compile_features ( ${PROJECT_NAME} PUBLIC cxx_std_14 target_link_libraries ( ${PROJECT_NAME} PRIVATE ${PRJ_LIBRARIES} )

打开vscode，有：

此时vscode自动构建build目录，并配置（configure,generate）：
