[Qgis-developer] MetaSearch core integration questions

Hi all: FYI MetaSearch [0] has been approved for inclusion in QGIS
core [1] [2].  I've started to work on the integration.  I originally
envisioned an automagic process using git merge/read-tree, however
given the issues below, I am finally realizing that a canned release
brute force dump might be the best thing as a first step.

My plan is to create a build process which exports a stable MetaSearch
for QGIS release.

The following issues exist:

- handling dependencies: MetaSearch requires OWSLib, pygments, and
Jinja2 [3] (and everything upstream of them that is not in the Python
standard library) and integrates these via pip.  For publishing to
plugins.qgis.org we bundle them into the .zip package into a dir call
ext-libs.  We can do the same for QGIS inclusion for now.  What is the
state of affairs in terms of QGIS build workflow / core support for
Python dependencies?  This would really move forward the Python plugin
(core Python plugins or installed via plugins.qgis.org) ecosystem
knowing that a few core Python libs are in core

- cmake: MetaSearch does build type things via Paver.  I've added
various CMakeLists.txt files in the code (not pushed yet), however if
I include the dependencies (see point above), does this mean I need to
add CMakeLists.txt files across the dependency directory structure
(for example, see current MetaSearch download at [4])?!

I hope the above is somewhat clear.  Admittedly I am new to the QGIS
build story and have only used cmake in my MapServer dev.  Thanks for
the help so far in irc.
