wangzhengyang 718c41634f feat: 切换后端至PaddleOCR-NCNN，切换工程为CMake 
1.项目后端整体迁移至PaddleOCR-NCNN算法，已通过基本的兼容性测试
2.工程改为使用CMake组织，后续为了更好地兼容第三方库，不再提供QMake工程
3.重整权利声明文件，重整代码工程，确保最小化侵权风险

use ncnn with own project

After building ncnn, there is one or more library files generated. Consider integrating ncnn into your own project, you may use ncnn's installating provided cmake config file, or by manually specify library path(s).

with cmake

Ensure your project is built by cmake. Then in your project's CMakeLists.txt, add these lines:

set(ncnn_DIR "<ncnn_install_dir>/lib/cmake/ncnn" CACHE PATH "Directory that contains ncnnConfig.cmake")
find_package(ncnn REQUIRED)
target_link_libraries(my_target ncnn)

After this, both the header file search path ("including directories") and library paths are configured automatically, including vulkan related dependencies.

Note: you have to change <ncnn_install_dir> to your machine's directory, it is the directory that contains ncnnConfig.cmake.

For the prebuilt ncnn release packages, ncnnConfig is located in:

  • for ncnn-YYYYMMDD-windows-vs2019, it is lib/cmake/ncnn
  • for ncnn-YYYYMMDD-android-vulkan, it is ${ANDROID_ABI}/lib/cmake/ncnn (${ANDROID_ABI} is defined in NDK's cmake toolchain file)
  • other prebuilt release packages are with similar condition

manually specify

You may also manually specify ncnn library path and including directory. Note that if you use ncnn with vulkan, it is also required to specify vulkan related dependencies.

For example, on Visual Studio debug mode with vulkan required, the lib paths are:

E:\github\ncnn\build\vs2019-x64\install\lib\ncnnd.lib
E:\lib\VulkanSDK\1.2.148.0\Lib\vulkan-1.lib
E:\github\ncnn\build\vs2019-x64\install\lib\SPIRVd.lib
E:\github\ncnn\build\vs2019-x64\install\lib\glslangd.lib
E:\github\ncnn\build\vs2019-x64\install\lib\MachineIndependentd.lib
E:\github\ncnn\build\vs2019-x64\install\lib\OGLCompilerd.lib
E:\github\ncnn\build\vs2019-x64\install\lib\OSDependentd.lib
E:\github\ncnn\build\vs2019-x64\install\lib\GenericCodeGend.lib

And for its release mode, lib paths are:

E:\github\ncnn\build\vs2019-x64\install\lib\ncnn.lib
E:\lib\VulkanSDK\1.2.148.0\Lib\vulkan-1.lib
E:\github\ncnn\build\vs2019-x64\install\lib\SPIRV.lib
E:\github\ncnn\build\vs2019-x64\install\lib\glslang.lib
E:\github\ncnn\build\vs2019-x64\install\lib\MachineIndependent.lib
E:\github\ncnn\build\vs2019-x64\install\lib\OGLCompiler.lib
E:\github\ncnn\build\vs2019-x64\install\lib\OSDependent.lib
E:\github\ncnn\build\vs2019-x64\install\lib\GenericCodeGen.lib
