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

[Luis Ibanez]

Hi Motes,

In Windows you can not select the compilation mode from CMake.

You have to do it from inside Visual Studio,
after you load the ITK solution file,
by selecting the configuration mode.

What version of Visual Studio do you use ?
