在windows下寫好CMakeLists.txt，然后配合cmake-gui使用。
CMakeLists.txt寫的不夠好，后期優化，以下僅供參考：
1 # set(OpenCV_DIR D:/Program Files/opencv3.4.6/opencv/build/include/) 2 find_package(OpenCV 3.4.6 REQUIRED) 3 4 # If the package has been found, several variables will 5 # be set, you can find the full list with descriptions 6 # in the OpenCVConfig.cmake file. 7 # Print some message showing some of them 8 message(STATUS "OpenCV library status:") 9 message(STATUS " version: ${OpenCV_VERSION}") 10 message(STATUS " libraries: ${OpenCV_LIBS}") 11 message(STATUS " include path: ${OpenCV_INCLUDE_DIRS}") 12 set(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} /MT") 13 set(CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS_DEBUG} /MTd") 14 set(LINK_DIR D:/windows/x64/Release/) 15 # Add OpenCV headers location to your include paths 16 include_directories(${OpenCV_INCLUDE_DIRS}) 17 18 # Declare the executable target built from your sources 19 20 aux_source_directory(. DIR_SRCS) 21 add_executable(main ${DIR_SRCS}) 22 23 # Link your application with OpenCV libraries 24 # link_libraries("D:/windows/x64/Release") 25 LINK_DIRECTORIES(${LINK_DIR}) #鏈接靜態庫目錄 26 target_link_libraries(main ${OpenCV_LIBS} ${LINK_DIR}/idcard.lib)
由於依賴opencv靜態庫，opencv又沒有設置為環境變量，cmake直接找依賴opencv時總是會找到Anaconda里面的opencv，此時需要把opencv路徑指定到你編譯opencv靜態庫的路徑：
也可以將CMakeLists.txt寫成下面的形式，這樣就可以自己在cmake-gui里面自己配置需要鏈接的靜態庫路徑：
1 # cmake needs this line 2 cmake_minimum_required(VERSION 2.8) 3 4 # Define project name 5 project(DLCropTest) 6 7 # Find OpenCV, you may need to set OpenCV_DIR variable 8 # to the absolute path to the directory containing OpenCVConfig.cmake file 9 # via the command line or GUI 10 # set(OpenCV_DIR D:/Program Files/opencv3.4.6/opencv/build/include/) 11 find_package(OpenCV REQUIRED) 12 find_library(LINK_DIR REQUIRED) 13 # If the package has been found, several variables will 14 # be set, you can find the full list with descriptions 15 # in the OpenCVConfig.cmake file. 16 # Print some message showing some of them 17 message(STATUS "OpenCV library status:") 18 message(STATUS " version: ${OpenCV_VERSION}") 19 message(STATUS " libraries: ${OpenCV_LIBS}") 20 message(STATUS " include path: ${OpenCV_INCLUDE_DIRS}") 21 set(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} /MT") 22 set(CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS_DEBUG} /MTd") 23 # set(LINK_DIR D:/windows/x64/Release/) 24 # Add OpenCV headers location to your include paths 25 include_directories(${OpenCV_INCLUDE_DIRS}) 26 27 # Declare the executable target built from your sources 28 29 aux_source_directory(. DIR_SRCS) 30 add_executable(main ${DIR_SRCS}) 31 32 # Link your application with OpenCV libraries 33 # link_libraries("D:/windows/x64/Release") 34 LINK_DIRECTORIES(${LINK_DIR}) #鏈接靜態庫目錄 35 target_link_libraries(main ${OpenCV_LIBS} ${LINK_DIR}/*.lib)
cmake-gui對應位置如下圖：
