As I travel down the compile path, I always make sure to follow and 
edit/update the BuildHints[1] wiki page for GDAL.  On that page MrSID 
instructions are also listed[2].  For example, for building on Windows I 
always must point to both the RASTER and LIDAR sdk's for this to work 
properly (the equivalent on unix would be --with-mrsid and 
--with-mrsid_lidar)

It would be great if you could update this buildhints page with your own 
hints/advice for others too, during your travels.
