windows CMakeLists.txt

在windows下写好CMakeLists.txt，然后配合cmake-gui使用。

CMakeLists.txt写的不够好，后期优化，以下仅供参考：

 # set(OpenCV_DIR D:/Program Files/opencv3.4.6/opencv/build/include/)

 find_package(OpenCV 3.4. REQUIRED)

 # If the package has been found, several variables will

 # be set, you can find the full list with descriptions

 # in the OpenCVConfig.cmake file.

 # Print some message showing some of them

 message(STATUS "OpenCV library status:")

 message(STATUS "    version: ${OpenCV_VERSION}")

 message(STATUS "    libraries: ${OpenCV_LIBS}")

 message(STATUS "    include path: ${OpenCV_INCLUDE_DIRS}")

 set(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} /MT")

 set(CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS_DEBUG} /MTd")

 set(LINK_DIR D:/windows/x64/Release/)

 # Add OpenCV headers location to your include paths

 include_directories(${OpenCV_INCLUDE_DIRS})

 # Declare the executable target built from your sources

 aux_source_directory(. DIR_SRCS)

 add_executable(main ${DIR_SRCS})

 # Link your application with OpenCV libraries

 # link_libraries("D:/windows/x64/Release")

 LINK_DIRECTORIES(${LINK_DIR}) #链接静态库目录

 target_link_libraries(main ${OpenCV_LIBS} ${LINK_DIR}/idcard.lib)

由于依赖opencv静态库，opencv又没有设置为环境变量，cmake直接找依赖opencv时总是会找到Anaconda里面的opencv，此时需要把opencv路径指定到你编译opencv静态库的路径：

也可以将CMakeLists.txt写成下面的形式，这样就可以自己在cmake-gui里面自己配置需要链接的静态库路径：

 # cmake needs this line

 cmake_minimum_required(VERSION 2.8)

 # Define project name

 project(DLCropTest)

 # Find OpenCV, you may need to set OpenCV_DIR variable

 # to the absolute path to the directory containing OpenCVConfig.cmake file

 # via the command line or GUI

 # set(OpenCV_DIR D:/Program Files/opencv3.4.6/opencv/build/include/)

 find_package(OpenCV REQUIRED)

 find_library(LINK_DIR REQUIRED)

 # If the package has been found, several variables will

 # be set, you can find the full list with descriptions

 # in the OpenCVConfig.cmake file.

 # Print some message showing some of them

 message(STATUS "OpenCV library status:")

 message(STATUS "    version: ${OpenCV_VERSION}")

 message(STATUS "    libraries: ${OpenCV_LIBS}")

 message(STATUS "    include path: ${OpenCV_INCLUDE_DIRS}")

 set(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} /MT")

 set(CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS_DEBUG} /MTd")

 # set(LINK_DIR D:/windows/x64/Release/)

 # Add OpenCV headers location to your include paths

 include_directories(${OpenCV_INCLUDE_DIRS})

 # Declare the executable target built from your sources

 aux_source_directory(. DIR_SRCS)

 add_executable(main ${DIR_SRCS})

 # Link your application with OpenCV libraries

 # link_libraries("D:/windows/x64/Release")

 LINK_DIRECTORIES(${LINK_DIR}) #链接静态库目录

 target_link_libraries(main ${OpenCV_LIBS} ${LINK_DIR}/*.lib)

cmake-gui对应位置如下图：
