[Qgis-developer] Config fails on find of spatialindex library

[William Kyngesburye]

Yes, spatialindex was remove from the source, so it's now an external dependency.  I started working out compilation details for OS X and got distracted :(

It has nothing to do with the GEOS spatialindex.h.

For detecting spatialindex in configuration, I see that spatialindex installs its headers in a subfolder of the include folder, and the cmake find spatialindex doesn't check this.  If you specify SPATIALINDEX_LIBRARY and SPATIALINDEX_INCLUDE_DIR it should be OK.

Once found, I see another problem - internally, spatialindex headers include each other by spatialindex/*/*.h.  But QGIS does not - I think it's previous internal spatialindex had these includes all changed.  ...and indeed, changing the one include in core/qgsspatialindex.cpp to:

#include <spatialindex/SpatialIndex.h>

does the trick.
