CodeLite IDE

Because debugger not support cdb, so, this option is no need for VC++ user.
Then, if it's a plugin, so, user can disable it.

or, have some option to off it?

If it really disturbs you that much, simply delete the dll named Debugger.dll under C:\Program Files\CodeLite\debuggers

Other than that, codelite was never built for VC, it was intended to be used with gdb / gcc mostly.
