Everytime CMakeToggle is triggered, origin buffer lose syntax highlight

[gzqx]

Bug description

~~After triggering :CMakeGenerate first time in every session, all text in origin buffer become white and have no highlight. (If I reopen the file in the same buffer or run syntax on, do some editing and re-run :CMakeGenerate, this does not happen)~~

After testing, this behavior is actually triggered by everytime :CMakeToggle is triggered. It seems that on first :CMakeGenerate or everytime :CMakeRun is ran in text buffer :CMakeToggle is called. (Sorry I didn't have the time to dig into the code to check if it is true)

Expected behavior

Hightlight does not disappear from the first time.

Behavior with minimal .vimrc

Same behavior with a minimal .vimrc as following:

set nocompatible
let &runtimepath  = '~/.vim/bundle/vim-cmake,' . &runtimepath
filetype plugin indent on
syntax enable

Same also happens when running :CMakeRun for the first time.

Hi, thanks a lot for reporting this.

I can indeed reproduce your issue. I believe PR #87 fixes it. Could you please try checking out branch 86-cmake-open-clears-syntax-hl and let me know if that indeed solves your problem?
