Ping. I had issues with building patch 5, but the rest of the series is in good shape IMO and can be merged independently at least. Is there anything more needs to be done to help get this support merged? Thanks -- Qais Yousef

The patch series is here: http://patchwork.ozlabs.org/project/buildroot/list/?series=221413 I didn't work on it since then, only the patch 5/5 needs to be reworked.

In my original posting I added install(TARGETS parser LIBRARY DESTINATION ${CMAKE_INSTALL_LIBDIR}) Which Romain suggested building as static is a better option.

If Romain doesn't get a chance to address your review comments soon enough I'll address them and post a new version. Both of us have been driving this during our free time on the weekends.
