Use gtags in Spacemascs

1) Install GNU global from source
https://www.gnu.org/software/global/download.html
./configure --with-exuberant-ctags=/usr/bin/ctags

2)config .spacemacs
(setq dotspacemacs-configuration-layers
      '( ;; ...
        gtags
         ;; ...
        ))

Enable by default

(setq-default dotspacemacs-configuration-layers
  '((gtags :variables gtags-enable-by-default t)))

3)generate GTAGS database
cd /your_project
gtags

There will be three new file in this folder:
GPATH, GTAGS, GRTAGS

DONE!
