You're referring to the initial pseudo build here I presume?
Yes.
But after I got to the UI of hob, I got
errors adding my layers to get to the meta-intel layers I wanted. So
I started over and edited local.conf and bblayer.conf prior to
launching hob. Now I could see my machine from meta-intel, but I
could not add my layer in. Parsing errors.
By parsing errors it would help if you were more specific. Do you mean the
following?
ERROR: Unable to parse /home/paul/poky/meta-intel/meta-
cedartrail/conf/layer.conf: Failure expanding variable BBPATH, expression was
${BBPATH}:/home/paul/poky/meta-intel which triggered exception Exception:
variable BBPATH references itself!
ERROR: Unable to parse /home/jim/poky/meta-hob/conf/layer.conf:
Failure expanding variable BBPATH, expression was
$(BBPATH):/home/jim/meta-jfa:/home/jim/poky/meta
which triggered exception Exception: variable BBPATH
references itself!
Before I report an error, I wanted to see if I have the hob startup
process right. The issues is around the right way to add
meta-intel/meta-cedartrail and my personal layer in my home directory.
Any advice?

My experimenting tells me that currently Hob (denzil) only work with new
added layers that are in the poky directory and not in your home
directory. This is a different requirement than normal command line
usage of bitbake.
Assuming the error you're seeing is the one above, I don't think that's the
problem - the problem AFAICT is that the order of the layers hob is using is
not the same as the order in which it displays them, and the order it uses is
not compatible with the old method of setting BBPATH which meta-intel and its
sub-layers use, which is 'BBPATH := "${BBPATH} /extra/path/to/add"' - if
BBPATH is not already set as it would not be if this is the first layer in the
list, then it is unable to expand BBPATH and you get this failure. You can
reproduce this outside of hob just by reordering the entries in bblayers.conf.
So there are a few issues highlighted here:
1) Hob is re-ordering the layer list and it definitely shouldn't be. I've filed
bug #2649 to get this fixed.
2) We really ought to go through and fix the BBPATH setting for all layers to
not use the old method of appending to it.
3) It may be useful for people to be able to change the order of layers in the
layer list within hob, particularly for situations where class/conf files are
overlayed (which is to be avoided, but does occur).
Cheers,

Seems that you understand the problem :-)
