How to specify where to generate the tag file

Question

I currently have a project directory such as

MainProject
|_ProjectA
|   |_src
|      |_file1.cpp
|      |_file2.cpp
|      |_.....
|      |_tags <---tag file generated here  
|_ProjectB
|   |_src
|      |_file3.cpp
|      |_file4.cpp
|      |_.....
       |_tags <---tag file generated here

Now file4.cpp uses the elements in file1.cpp, however it seems that since it is in a different folder, I get a message

cstag - tag not found

Currently I went into my ProjectA and ProjectB and did this for each

ctage -R .

as a result, a tag file is generated in each project. My question is how can I specify where to generate the tag file. In this case, all the tag files will be next to each other and, hopefully, this will solve this problem.

Answer 1

The simplest solution would be to create a single file tags:

$ cd MainProject
$ ctags -R .

Vim , tags:

set tags=./tags;,tags;
