[Insight-developers] Can't find itkpng.lib; don't need it anyway.

[Luis Ibanez]

Hi Mark,

itkpng.lib is added to the link list because the ImageIOFactories
have several file formats registered by default.

The defaults are: { PNG, MetaImage, Dicom, VTK }

As long as you use any IO in your program, the libraries
associated with these default formats will enter into the
dependencies.

The need for the LINK_DIRECTORIES will be solved by the
current ongoing process of placing all libraries and
executables in a single common directory.

You shouldn't need to add "Debug" to the paths.
The CMakeLists.txt files are independent of the build
configuration.
