configure is typically not used when building with cmake** so giving extra
options for it probably won't help. The reason there is a configure file at
all is that the project seems to support both autotools and cmake**. If you
want to continue with cmake, find out how it does the equivalent of
"--with-external-capnp": probably with something like "-DEXTERNALCAPNP" in
EXTRA_OECMAKE. The other alternative is to use autotools instead of cmake
(and add "--with-external-capnp" in EXTRA_OECONF).

I would suggest picking the build system the main developers actually use
or recommend, then figuring out how to build that with the options you need
_outside of yocto_, and then doing the same with a yocto recipe (keeping an
eye on $WORKDIR/temp/log.* so you know what the build/configure is actually
doing).


**) For reasons some people want multiple build systems in their projects.
As if one wasn't painful enough.
