[ITK] Compilation errors

[Matt McCormick]

Hello Apoorva,

Welcome to ITK!


These messages indicate possible issues with the CMake configuration.


For more information, see the "Configuring and Building ITK" section
of the ITK Software Guide:

  https://itk.org/ITKSoftwareGuide/html/Book1/ITKSoftwareGuide-Book1ch2.html#x22-130002

and find a downloadable HelloWorld example that includes the CMake
configuration here:

  https://itk.org/ITKExamples/src/Core/Common/BuildAHelloWorldProgram/Documentation.html


Hope this helps,
Matt
