1、Very simple executable

PROJECT( helloworld )   # 非必需

SET( hello_SRCS hello.cpp )

ADD_EXECUTABLE( hello ${hello_SRCS} )

1

2

3

说明：

ADD_EXECUTABLE creates an executable from the listed sources

Tip: add sources to a list (hello_SRCS), do not list them in ADD_EXECUTABLE

2、Very simple library

PROJECT( mylibrary )  #非必需

SET( mylib_SRCS library.cpp )

ADD_LIBRARY( my SHARED ${mylib_SRCS} )

1

2

3

说明：

ADD_LIBRARY creates an static library from the listed sources

Add SHARED to generate shared libraries (Unix) or dynamic libraries (Windows)

不加SHARED 生成.a 静态库，加了SHARED ，生成.so 动态链接库

3、Process a list

FOREACH(loop_var)

...

ENDFOREACH(loop_var)

4、3rd party or .h

If the 3rd party library or .h is in a “standard”:

directory (PATH and/or LD_LIBRARY_PATH) is automatic

If in a non­standard dir:

Headers: use INCLUDE_DIRECTORIES

Libraries: use FIND_LIBRARY and link with the result of it

cmake_minimum_required(VERSION 2.8)

project (faceIdentification)

file(GLOB_RECURSE srcs ${CMAKE_CURRENT_SOURCE_DIR}/*.cpp)

set(CMAKE_BUILD_TYPE "Release")

set(CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS} -std=c++11 -O2 -g -ggdb")

set(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS} -std=c++11 -O2")

find_package(Caffe)

include_directories(

${PROJECT_SOURCE_DIR}/include

${Caffe_INCLUDE_DIRS})

add_definitions(${Caffe_DEFINITIONS})

foreach(source ${srcs})

get_filename_component(name ${source} NAME_WE)

add_executable(${name} ${source})

target_link_libraries(${name}

${PROJECT_SOURCE_DIR}/lib/libviplnet.so

${Caffe_LIBRARIES})

endforeach(source)

附录

1、几种常用的库的CMakeLists.txt

boost

set(Boost_USE_STATIC_LIBS OFF)

set(Boost_USE_MULTITHREADED ON)

set(Boost_USE_STATIC_RUNTIME OFF)

find_package(Boost 1.45.0 COMPONENTS *boost libraries here*)

if(Boost_FOUND)

include_directories(${Boost_INCLUDE_DIRS})

add_executable(progname file1.cxx file2.cxx)

target_link_libraries(progname ${Boost_LIBRARIES})

endif()

# 将*boost libraries here* 替换为你需要的boost子库 ，如：filesystem 等

protobuf 链接库

include(FindProtobuf)

find_package(Protobuf REQUIRED)

include_directories(${PROTOBUF_INCLUDE_DIR})

...

target_link_libraries(progname

${PROTOBUF_LIBRARY}

)

protobuf 用 protoc 编译xxx.proto 文件生成cpp与.h

cmake_minimum_required(VERSION 2.8)

set(CMAKE_VERBOSE_MAKEFILE ON)

find_package(Protobuf REQUIRED)

PROTOBUF_GENERATE_CPP(PROTO_SRCS PROTO_HDRS Express.proto)

add_library(foo ${PROTO_SRCS} ${PROTO_HDRS})

target_link_libraries(foo ${PROTOBUF_LIBRARIES} pthread) #foo 链接 protobuf与pthread

OpenCV

find_package(OpenCV REQUIRED)

message(${OpenCV_INCLUDE_DIRS})  # 非必需

message(${OpenCV_LIBS})          # 非必需

include_directories(${OpenCV_INCLUDE_DIRS})

target_link_libraries(progname

${OpenCV_LIBS}

)

#或者可以设置一个非常有用的宏变量 OpenCV_DIR="your/path/include/OpenCVConfig.cmake file"

find_package(OpenMP REQUIRED)

if (OPENMP_FOUND)

message("found")

set (CMAKE_C_FLAGS "${CMAKE_C_FLAGS} ${OpenMP_C_FLAGS}")

set (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${OpenMP_CXX_FLAGS}")

endif()

2、多级目录下的CMakeLists.txt

.

├── CMakeLists.txt   #顶层目录下

├── include

│   ├── demo.h

│   └── detec.h

├── lib

├── src

│   ├── demo.cpp

│   ├── detec.cpp

│   └── proto

│       ├── CMakeLists.txt  #子目录

│       └── myProto.proto

└── tools

└── pipe.cpp

#只需在顶层CMakeListst.txt 加上如下两句话，就会自动执行子目录下的CMakeLists.txt

add_subdirectory(${PROJECT_SOURCE_DIR}/src/proto)

include_directories(${PROJECT_BINARY_DIR}/src/proto)
