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)

# 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})
