Ahhhh... rrgghh!  Some weird Xcode magic going on here.  Xcode makes  
use of header map (.hmap) files to locate intermediate and target  
headers, in addition to standard -I flags you may add to a target.   
One of these hmaps that is included in every target (!) is the  
location of ALL headers in the whole project.  hmap flags are all  
before the target defined header paths, so they are searched first.

Since many/most of the plugins use the same source file names, from  
the plugin template, there is confusion.  And for just this target, it  
was finding the ui_pluginguibase.h from the copyrightlabel plugin first.

I expect there will be more problems on a complete rebuild.  I was  
building targets for each plugin before creating the target for the  
next, so early plugins don't have ui headers from later plugins in  
their hmaps yet.


Possible solutions:

- rename plugin headers to include the plugin name. A big change in  
the source layout. But a test with the current northarrow plugin ui  
header worked.

- find an Xcode option to NOT include the all-project headers.  I'll  
dig around.  I may try that cmake xcode generator to see if it has any  
hints.

- add headers to the target, then they'll be added to the target hmap,  
which is searched before all others.  This did not work.
