Not to flog a dead horse here, but i do have something useful to add:

It is something of a pain, but not _every_ library needs it.  Only those
that do things like share the heap or pass file descriptors.  Let me give an
example.  My project (VTP) has around 16 library dependencies.  Some need to
be built on the same runtime library (and runtime version!), some do not:

Must be built with same runtime (/MDd vs. /MD, VC7.1 vc. VC8):
------------------
GDAL
wxWidgets
OSG, OpenThreads
zlib (if using the gzdopen function)

Does not need to match (Can be /MD, or built with older or non-VC compiler):
-------------------
libpng
libjpeg
libcurl
netcdf
QuikGrid
bzip2
expat
freetype
libMini
PROJ.4
unzip
zlib (if not using the gzdopen function)

You can put your debug and release DLLs (e.g. gdal.dll and gdald.dll) in the
same folder on your path so there is nothing to switch.
