This file is created the first time you try to run GNU Radio, so not
during build or even install. It /will/ get created when you run 'make
test' or any other GNU Radio application.

Is this on Windows? I'm honestly not sure what the right factory
function is for Windows, but my guess is this file should contain:

gr::vmcircbuf_createfilemapping_factory

Note that that's just one line, no carriage return or anything else.
