[Insight-users] Speeding up the evaluation of the itk::Gaussian?

[motes motes]

Now I have done the above (build itk from VS in Release mode and build
my application using the itk Release build in release mode) but
instead of:

Error   12      fatal error LNK1181: cannot open input file 'ITKCommon.lib'


I get a new error:

Error	12	fatal error LNK1181: cannot open input file
'StandardGradientDescent.lib'


Any ideas?

And why does these errors suddenly appear when I chose to build a
release build instead of Debug build?
