[Qgis-developer] Interpolation plugin

[Tim Sutton]

Hi Marco

I made a quick patch so that you can build it out of qgis source tree.
The install prefix in cmake .. will be ignored - the plugins will go
into your qgis plugins dir based on which qgis instance you are using.
I build like this:

ccmake .. -DQGIS_CORE_LIBRARY=/home/timlinux/apps/lib/libqgis_core.so
-DQGIS_GUI_LIBRARY=/home/timlinux/apps/lib/libqgis_gui.so
-DQGIS_PLUGIN_DIR=/home/timlinux/apps/lib/qgis/
-DQGIS_INCLUDE_DIR=/home/timlinux/apps/include/qgis/

I made a quick test run using the points layer in qgis tests/testdata
and it worked great!

Regards

Tim
