- Fixed Linux Build Error

Suggested by @Erdragh, seems like setting the linkage
for the dawn library could fix the linux build problem,
and not impacted to other platform because running
a testing triangle shader program with zgpu on
windows still works without any issue.

Let's see if this version could pass.
