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

Log: 切换后端至PaddleOCR-NCNN,切换工程为CMake

# Arm semihosting
This folder contain a toolchain file and a couple of examples for
building OpenCV based applications that can run in an [Arm
semihosting](https://developer.arm.com/documentation/100863/latest)
setup.
OpenCV can be compiled to target a semihosting platform as follows:
```
cmake ../opencv/ \
-DCMAKE_TOOLCHAIN_FILE=../opencv/platforms/semihosting/aarch64-semihosting.toolchain.cmake \
-DSEMIHOSTING_TOOLCHAIN_PATH=/path/to/baremetal-toolchain/bin/ \
-DBUILD_EXAMPLES=ON -GNinja
```
A barematel toolchain for targeting aarch64 semihosting can be found
[here](https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-a/downloads),
under `aarch64-none-elf`.
The code of the examples in the `norm` and `histogram` folders can be
executed with qemu in Linux userspace:
```
qemu-aarch64 ./bin/example_semihosting_histogram
qemu-aarch64 ./bin/example_semihosting_norm
```
