Ayman,

Norman is right on this, though you can only control what gets
included by subdirectory of gdal/frmts, so for instance, to get any
driver in the frmts/raw directory you normally get them all.  However, they
are "light".  There are also a few dependencies between drivers that may come
up.

I would add that you can save alot by not including the OGR drivers in a GDAL
build where you only need raster support.

On windows set comment out the "INCLUDE_OGR_FRMTS" flag setting to disable
inclusino of OGR.

On Unix configure with the "--without-ogr" switch.
