rasterlite support should not be conditionalized on just sqlite

[kyngchaos]

In gdalmake.opt.in, compilation of rasterlite support is based on sqlite:

ifeq ($(OGR_ENABLED),yes)
ifeq ($(HAVE_SQLITE),yes)
GDAL_FORMATS := $(GDAL_FORMATS) rasterlite
endif
endif

Having Sqlite does not necessarily mean librasterlite is available. There is a macro for spatialite, HAVE_SPATIALITE, but even that does not mean rasterlite is available (ie because rasterlite is GPL, it may not be included with the BSD-like spatialite). Rasterlite needs its own HAVE_RASTERLITE.

It also has its own library, so simply linking libspatialite won't work.

Hmm, so I may be overreacting - this was based on reviewing the new features and assuming rasterlite support needs librasterlite. Now I compile - without librasterlite available, but with sqlite+spatialite - no compile or link errors.

Does rasterlite support need librasterlite?

William,

why not reading the doc to check your assumptions ;-) : ​http://gdal.org/frmt_rasterlite.html ?

Not linking against librasterlite is a design decision to avoid GPL dependency
