This reverts commit a1fe671db8.
Lue suggested reverting #661 because ZLS worked around the issue of @src
being relative in that environment: https://github.com/zigtools/zls/pull/898
This is not a perfect solution (what zls did seems to be a workaround), but
is good enough for us until Zig gets an official package manager.
