I will add documentation about this to the site [0]. I have been debugging
this setup and now having it working smoothly on Mac 10.7.5 and 10.9.2. You
can use the following notes for now and we can work on making the online
docs better, eventually including it in INSTALL somehow.

Basic instructions:

1) Ensure deps are installed:

Install required build Python modules (use pip on system or Homebrew's pip
when using its Python). You can also tap homebrew/python for some more
complex modules [1]:

* numpy  <-- this is used by gdal.rb install, if building with python
option, which is the default

$ brew tap homebrew/science
$ brew tap dakcarto/osgeo4mac
$ brew install qgis-22 --only-dependencies --with-grass --with-globe
[--with-oracle]

Install required run-time Python modules :

* psycopg2 matplotlib pyparsing

2) Copy the following directory elsewhere and use it from there:
HOMEBREW_PREFIX/Library/Taps/dakcarto-osgeo4mac/scripts

Note: it's important to not edit the scripts where they are located, in the
tap, because it is a git repo. You should keep that working tree clean so
that `brew update` always works.

Open and review scripts:

* qgis-cmake-options.py - for generating CMake option string for use in Qt
Creator when built off dependencies from homebrew-osgeo4mac tap. Edit CMake
options to suit your build needs. Note, the current script usually has
CMake options for building QGIS with *all* options that the current
Homebrew formula, e.g. qgis-22, supports, which can include things like
Oracle support, etc. You will probably want to edit it and comment out such
lines for an initial build. I add this as an external tool in Qt Creator
[2].

* qgis-set-app-env.py - for setting env vars in dev build and installed
QGIS.app, to ensure they are available on double-click run. Needs to stay
in the same directory as the next scripts.

* qgis-creator-build.sh - sets up the build environ and ensures the
QGIS.app in the build directory can find resources, so it can run from
there.

* qgis-creator-install.sh - installs the app and ensures QGIS.app has
proper env variables, so it can be moved around on the filesystem.
Currently QGIS.app bundling beyond QGIS_MACAPP_BUNDLE=0 is not supported.

3) Configure a Creator Qt version and kit [3, 4].

4) Configure Creator project with prepended environment variables and to
use the build and install scripts [5].

This whole setup supports builds where the OSGeo4Mac deps are in a
non-standard Homebrew location, e.g. /usr/local/osgeo4mac or
/opt/osgeo4mac, instead of /usr/local. This allows for multiple build
scenarios, including placing the deps on an external drive, though that
requires building all deps with special 'bottle' parameters.

I've tried to make the setup as simple and flexible as possible, though I'm
sure it can use some work.

Let me know how it goes!  :-)
