CMake 一些语法

1.message语法 打印信息

message( [STATUS|WARNING|AUTHOR_WARNING|FATAL_ERROR|SEND_ERROR]
  "message to display" ...)

可以用下述可选的关键字指定消息的类型:

(无) = 重要消息;
 STATUS = 非重要消息;
 WARNING = CMake 警告, 会继续执行;
 AUTHOR_WARNING = CMake 警告 (dev), 会继续执行;
 SEND_ERROR = CMake 错误, 继续执行,但是会跳过生成的步骤;
 FATAL_ERROR = CMake 错误, 终止所有处理过程;

输出变量的值:

SET(USER_KEY, "Hello World")
MESSAGE(STATUS "this var key = ${USER_KEY}.")

caffe cmakelist 1

在caffe源码tools目录下,目录结构如下:

├── caffe.cpp
├── caffe_test_c.cpp
├── CMakeLists.txt
├── compute_image_mean.cpp
├── convert_imageset.cpp
├── extra
│   ├── extract_seconds.py
│   ├── launch_resize_and_crop_images.sh
├── extract_features.cpp
├── upgrade_net_proto_binary.cpp
├── upgrade_net_proto_text.cpp
└── upgrade_solver_proto_text.cpp

这里面的cmakelist就是把每个cpp生成一个可执行文件。

可以学习学习写法:

# Collect source files
file(GLOB_RECURSE srcs ${CMAKE_CURRENT_SOURCE_DIR}/*.cpp)

#MESSAGE(STATUS "srcs = ${srcs}.")

MESSAGE(STATUS "Caffe_LINK = ${Caffe_LINK}")

# Build each source file independently
foreach(source ${srcs})
  get_filename_component(name ${source} NAME_WE)
  MESSAGE(STATUS "name = ${name}")

  # caffe target already exits
  if(name MATCHES "caffe")
    MESSAGE(STATUS "MATCHES name = ${name}")
    set(name ${name}.bin)
  endif()

  # target
  add_executable(${name} ${source})
  target_link_libraries(${name} ${Caffe_LINK})
  caffe_default_properties(${name})

  # set back RUNTIME_OUTPUT_DIRECTORY
  caffe_set_runtime_directory(${name} "${PROJECT_BINARY_DIR}/tools")
  caffe_set_solution_folder(${name} tools)

  # restore output name without suffix
  if(name MATCHES "caffe.bin")
    set_target_properties(${name} PROPERTIES OUTPUT_NAME caffe)
  endif()

  # Install
  install(TARGETS ${name} DESTINATION ${CMAKE_INSTALL_BINDIR})

endforeach(source)

一般独立的生成一个可执行文件写法:

cmake_minimum_required(VERSION 3.0 FATAL_ERROR)
project(test_glogs)
 
SET(CMAKE_BUILD_TYPE Debug)
 
#glog
include_directories(/data_2/lib/glog/include/)
link_directories(/data_2/lib/glog/lib)
 
add_executable(main main.cpp)
target_link_libraries(main glog)
set_property(TARGET main PROPERTY CXX_STANDARD 11)
