1.使用vcpkg安装opencv库

1
./vcpkg install opencv:x64-windows --head --clean-after-build

2.在cmake中引入vcpkg管理的qt6静态库

1.main.cpp

#include <QCoreApplication>

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
    qDebug("hello,world\n");
    qDebug() << "hi:" << "see you";
    return a.exec();
}

# 移除或修改三元组：改为动态版本 x64-windows
#set(VCPKG_TARGET_TRIPLET x64-windows)

project(FinalApp VERSION 0.1  LANGUAGES CXX C)

# 基础编码与标准设置
if(MSVC)
    add_compile_options(/utf-8)
endif()

# 设置 C++ 标准
set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

# 4. 查找 OpenCV
find_package(OpenCV REQUIRED)

# 添加可执行文件
set(SOURCE main.cpp)
add_executable(${PROJECT_NAME} ${SOURCE})

# 输出到项目下的 bin 文件夹
set_target_properties(${PROJECT_NAME} PROPERTIES
        RUNTIME_OUTPUT_DIRECTORY "${CMAKE_SOURCE_DIR}/bin/$<CONFIG>"
)
#  链接库
target_link_libraries(${PROJECT_NAME}  PRIVATE
        ${OpenCV_LIBS}
)

{
  "version": 3,
  "configurePresets": [

    {
      "name": "base-global",
      "hidden": true,
      "cacheVariables": {
        "CMAKE_EXPORT_COMPILE_COMMANDS": "YES",
        "CMAKE_TOOLCHAIN_FILE": "C:/D/test/CCpp/ccpplib/vcpkg/vcpkg/scripts/buildsystems/vcpkg.cmake"
      }
    },

    {
      "name": "base-ninja",
      "hidden": true,
      "generator": "Ninja",
      "binaryDir": "${sourceDir}/out/build/${presetName}"
    },

    {
      "name": "base-msvc",
      "hidden": true,
      "architecture": { "value": "x64", "strategy": "external" },
      "toolset": { "value": "host=x64", "strategy": "external" },
      "cacheVariables": {
        "CMAKE_C_COMPILER": "cl.exe",
        "CMAKE_CXX_COMPILER": "cl.exe"
      },
      "vendor": {
        "jetbrains.com/clion": { "toolchain": "MSVC" }
      }
    },

    {
      "name": "opencv-debug",
      "displayName": "OpenCV MSVC Debug",
      "inherits": ["base-global", "base-ninja", "base-msvc"],
      "cacheVariables": {
        "CMAKE_BUILD_TYPE": "Debug",
        "VCPKG_TARGET_TRIPLET": "x64-windows",
        "X_VCPKG_APPLOCAL_COPY_INSTALL": "ON"
      }
    },

    {

  ],
  "buildPresets": [
    { "name": "debug", "configurePreset": "opencv-debug" },
    { "name": "release", "configurePreset": "opencv-release" }
  ]
}

4.命令行构建编译命令：

  • x64 架构：打开 **”x64 Native Tools Command Prompt for VS 2022”**。此时运行 cl.exe 会默认输出 x64 目标代码。
  • x86 架构：打开 **”x86 Native Tools Command Prompt for VS 2022”**。

如果已经在普通 CMD 中，可以通过调用脚本切换（注意必须使用 call）：

1
call "C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Auxiliary\Build\vcvarsall.bat" x64
  1. 构建配置

cmake .. -B build -S . -G "Ninja" `

  -DCMAKE_TOOLCHAIN_FILE="C:/D/test/CCpp/ccpplib/vcpkg/vcpkg/scripts/buildsystems/vcpkg.cmake" `
  -DVCPKG_TARGET_TRIPLET=x64-windows

  -DOpenCV_DIR="C:/D/test/CCpp/ccpplib/vcpkg/vcpkg/installed/x64-windows-static/share/opencv4" `
  -DCMAKE_BUILD_TYPE=Release `
  -DCMAKE_C_COMPILER=cl.exe `
  -DCMAKE_CXX_COMPILER=cl.exe `
  1. 编译

debug

1
cmake --build . --config Debug

release

1
cmake --build . --config Release

5.使用cmakepresent.json构建编译脚本

@echo off
:: 1. 自动挂载 MSVC 环境
call "C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Auxiliary\Build\vcvarsall.bat" x64
:: 2. 运行 CMake Preset
cmake --preset=opencv-release
:: 3. 运行构建
cmake --build --preset=release -j8
