[Insight-developers] Building GaussianFilter Example /MetaImageIO

[Luis Ibanez]

Thanks for the instructions, the changes were made.

However I was thinking more in the way RPM works:

if you select on package, it will activate all the
requirements too.

That is, if I select to build GaussianFilter, it 
would be nice if MetaImage (previously marqued as
a requirement) will be enabled during the CMake
analysis of the CMakeList.txt files.

Maybe it is just something for a wish list...
