Morning,
I'm attempting to compile the QGIS 2.8.1 grass plugin against GRASS
7.0.0 on Arch Linux 64bit.
I read somewhere (maybe GIS.se?) that the GRASS plugin in QGIS doesn't
have full functionality and a kickstarter/crowdfunding process could be
underway to get it up to par, but in the meantime it was also mentioned
it's still possible to use the toolbar to load grass 7 layers into the
qgis canvas.
GDAL 1.11.2 is installed and so is gdal-grass plugin using some patches
to get GDAL working with grass 7.
I'm using the following cmake options in the QGIS build:
-DWITH_GRASS=ON
-DGRASS_PREFIX=/opt/grass
-DGRASS_INCLUDE_DIR=/opt/grass/include
But QGIS fails to build with the following error:

So I'm not sure what the hiccup is exactly. GRASS 7 is installed and
runs fine outside of QGIS, but maybe it's missing some environment
variables (like GISRC or GISDBASE) that QGIS needs to compile against it?
