spatialindex includes in subfolder, not found by qgis

The standard spatialindex installation places its headers in a subfolder of $prefix/include, ie @/usr/local/include/spatialindex/@. The cmake FindSpatialitindex does not check for this, but I'm not sure if that is broken, as I am installing in a non-standard location.

But, qgsspatialindex.cpp also does not include from the subfolder. A leftover from when spatialindex was included in the source and didn't have the subfolder. Changing the qgsspatialindex.cpp include to:

#include <spatialindex/SpatialIndex.h>

fixes the include problem. The findspatialindex.cmake probably needs a similar fix.

@SPATIALINDEX_INCLUDE_DIR@ is the directory where @SpatialIndex.h@ is, so @FindSpatialindex.cmake@ should set it to @/usr/local/include/spatialindex@ in your case - and @#include "SpatialIndex.h"@ should work just fine.

Ah. But then spatialindex has a bug. I looked at all its internal headers included by spatialindex.h, and they are indeed local off the subfolder. Except Point.h, it causes the include error I saw with this:

#include <spatialindex/tools/Tools.h>

If you install spatialindex in a standard location like /usr/local you probably won't see an error because /usr/local/include will likely also be in your compile command.

So, invalid QGIS bug. Over to spatialindex folks...
