cmake中list,set的对字符串操作

cmake中所有的对象都是string，所以我们对这些的操作就是对字符串的操作，里面提供追加和删除的方法

 CMakeLists.txt

cmake_minimum_required(VERSION 3.15)
project(test)
# 方式二
file(GLOB SRC ${CMAKE_CURRENT_SOURCE_DIR}/src/*.cpp)
message("=========================")
message(${SRC})
list(REMOVE_ITEM SRC ${CMAKE_CURRENT_SOURCE_DIR}/src/main.cpp)

message("=========================")
message(${SRC})
# 添加头文件
include_directories(${PROJECT_SOURCE_DIR}/include)
# set(EXECUTABLE_OUTPUT_PATH ../output)
set(CMAKE_CXX_STANDARD 11)
# 生成依赖库文件路径
set(LIBRARY_OUTPUT_PATH ../share)
# add_executable(app ${SRC})
# add_library(calc STATIC ${SRC})
set(tmp hello world)
set(tmp1 ${tmp} ${SRC})
message(${tmp})
message(${tmp1})
list(APPEND tmp "xxxx")
message(${tmp})
