Maybe.  But if so, then qgis_core would have failed also, since that links GDAL also and is compiled first.

One thing to try is a simple "make".  Sometimes the parallel compilation can get ahead of itself (maybe some dependency isn't properly waited for?) and you get errors.

Also, to see all the gory details of the compilation (may help figure out if some other GDAL is linking), add this to the cmake configuration:

-D CMAKE_VERBOSE_MAKEFILE=true
