Everytime after load a cscope.out in Vim, I need to change Vim\'s \"pwd\" to the same directory as cscope.out file is under, which might be due to that cscope use relative path
When importing cscope.out, you can supply the prefix, i.e.
:cscope add /path/to/cscope.out /path/to/src/code
Then your searches will turn up like:
Cscope Tag: foobar # line filename / context / line 1 21 /path/to/src/code/foobar_file.c
