Looking at 'vs-code-template.code-workspace', it seems to just include 
the whole source tree as a directory, so I suspect that there's no 
problem since simply all header and source files in there will be included:


         ...
         "folders": [
                 {
                         "name": "srcdir",
                         "path": "/home/michi/development/git/libreoffice"
                 },

See my other mail from just now, this should hopefully work with 
different autogen options.
