Is there a dependency missing? Using this new packageconfig fails with
the following error during do_configuration:

(Please keep the discussion on the mailing list)

I have enabled the fastcv PACKAGECONFIG in my run, since that's the
point of having it, isn't it? With that it has -DWITH_FASTCV=ON amonst
the CMake flags, and that part seems to work as it should.
Did enabling this new PACKAGECONFIG flag work for you?

Hi, 
 
It should not download the tar file when FastCV is disabled.  Try
sourcing the env again and check for the flag : DWITH_FASTCV=OFF in the
configure file.

I think we need to download it along with other dependencies in
SRC_URI or provide a separate recipe for fastcv, at times we have
housed dependencies in packageconfig which may come
from other layers as long as they are off by default. In fastcv's case
I think the recipe does not exist in any known layer either.
my intention was to add a note so we remember why we disabled it so
perhaps just adding a comment would be fine.
