Re: [cdt-dev] Mozilla now has built-in support for CDT project generation
That is what I was referring too, but you cannot call this from phyton.
So ideally headless app would not allow indexer to kick in at all (because it is not needed for headless build/import)

Here's how it's done:
http://mxr.mozilla.org/mozilla-central/source/python/mozbuild/mozbuild/backend/cpp_eclipse.py#125

I disable the indexer by writing to
'.settings/org.eclipse.cdt.core.prefs', I import the project using 'org.eclipse.cdt.managedbuilder.core.headlessbuild' and restore the indexer.

If we see breakage from time to time I'll contribute a patch. I'm hoping to get the indexer closer to 100% first.
