**Describe the bug** In ubuntu (16.04 14.04）and many other Linux distribution, "sh" links to /bin/sh not /bin/bash. build-thirdparty.sh use source command which only exists in /bin/bash not /bin/sh. Run build-thirdparty.sh by sh fails and downlaod-thirdparty.sh:65 use sh to run download-thirdparty.sh. Because both first line of download-thirdpaty.sh and build-thirdparty.sh is "#!/bin/bash", the bash scripts can run directly without “sh".
**To Reproduce** Steps to reproduce the behavior: 1. sh ./thirdparty/build-thirdparty.sh 2. See error: thirdparty/build-thirdparty.sh: 41: thirdparty/build-thirdparty.sh: source: not found **Expected behavior** build third-party source **Screenshots**  **Desktop (please complete the following information):** - OS: Ubuntu - Version 16.04 **Additional context** Add any other context about the problem here.
