[Insight-users] Re: Simple 3D Gaussian Blur problem

[John.David Q]

I have answered my own question.

By using the cmake GUI instead of typing "cmake .", the compiled
program performs correctly and without error.

For reference, I am using:
Windows XP
CMake 2.4 - patch 2
ITK 2.6.0
Visual Studio 7 2003
