Merge pull request #21531 from fengyuentau:add_3rdparty_mirrors Support downloading 3rdparty resources from Gitcode & Gitlab-style mirrors * replace github.com with gitcode.net for ocv_download * replace raw.githubusercontent.com with gitcode.net for ocv_download * rename funtions and remove some comments * add options for custom mirrors, which simply replace domain github.com & githubusercontent.com * run ocv_init_download once; replace DL_URL with mirrored one when calling ocv_download * fix for empty download links when not using mirror * fix bugs: set(.. .. PARENT_SCOPE) for ocv_init_download; correct macro names for replace github archives and raw githubusercontent * adjusted mirror swapping impl: replace with mirrored link before each ocv_download; update md5sum for archives * fix a bug: macro invoked with incorrect arguments by non-set vars * enclose if statement * workable impl * shorten the var names of two key options * scalable implementation of downloading from mirror and using custom mirror * improve ocv_init_download help message * fix the different extracted directory name in case of ADE & TBB which are downloaded from release page * improve help message printing * Download ADE & TBB using commit ids instead of from release pages * support custom mirrors on downloading archives * improve hints * add missing parentheses * reset ocv_download calls * mirror support implementation using ocv_cmake_hook & ocv_cmake_hook_append * move ocv_init_download into cmake/OpenCVDownload.cmake * move ocv_cmake_hook before checking CMake cache * improve hints when not fetching as git repo * add WORKING_DIRECTORY in execute_process in ocv_init_download * use OPENCV_DOWNLOAD_MIRROR_ID * add custom.cmake for custom mirror * detect github origin * fix broken var name * download from github by default if custom tbb is set * add checksum checks for gitcode.cmake before replacing urls and checksums * add checksum checks for custom.cmake before replacing urls and checkusms * use description specify instead of set for messages in custom.cmake; use warning message for warnings * updates and fixes
