问题重现：
$ git clone -b v2.24.0 https://github.com/XXXX/librealsense.git
报错
Cloning into ‘librealsense’… fatal: unable to access
‘https://github.com/IntelRealSense/librealsense.git/’:
gnutls_handshake() failed: The TLS connection was non-properly
terminated.
解决方法：
将命令中的 https改为 git
git clone -b v2.24.0 git://github.com/XXXX/librealsense.git
