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

# Commandline parameters:
# $@ These are the names of the packages to check with 'dpkg'. Multiple values may
# be specified per package by using pipe as a delimiter, e.g. libpng-dev|libpng12-dev.
# Multiple values are evaluated left-to-right and the first found prevents checking of
# the remaining package options.

# -o <package_name> Specifying this switch with a package name marks it as optional
