[Qgis-user] Postgres dependency on mac build

[William Kyngesburye]

Puzzling why it's not finding Postgres without any options.

But, the CONFIG option should point to a file (pg_config), not a  
folder. (Same goes for library options, but not for include dir options)

I've noticed that the "Found ..." feedback is not always correct, or  
you just have to read more into what it says.  Like your Postgres  
response: it says "it's a directory", which can mean "it's not  
supposed to be a directory".

Also, when reconfiguring, make sure to clean first, or it may remember  
the previous configuration.  Cleaning is not thorough in cmake, so the  
easiest way is to build outside the source.  ie:

in the qgis source dir,

mkdir build-osx
cd build-osx
cmake [your options] ..

(note the .. instead of . for the source dir option)  Then you can  
just trash the contents on build-osx to clean, before reconfiguring.
