Dear Jian,
this issue can be at least for the moment solved by installing the GLFW packages on your system, see in another ALICE talk ticket this comment from Sandro and, further down in the same ticket, my comment. In my comment you find the line to install the needed GLFW packages on Ubuntu 18.04. Here is a link to the QuickStart page with instructions for CC7 and Mac.
For the experts: In that other ticket I asked to update the QuickStart page with both the information, that GLFW is obligatory for the moment, and with the install command for Ubuntu. I really would suggest to add this information there.
Cheers,
Stefan
