Comment (by jeremyhu@…):

 Moving from autotools to cmake as the build system is not exactly the fix.
 It might fix this as a side effect (I haven't tested), but in itself, that
 is not the fix.  That being said, if you want to provide a patch to get us
 onto the new build system, I'd certainly appreciate it.
