Ah, of course, I forgot to re-enable ITKGroup_Filtering and
ITKGroup_IO for my fresh build. The headers are indeed copied with
'make install' with the modules enabled. I don't suppose there would
be some way of catching a "missing header" error like that and
contributing it to "you need to enable XYZ module"?

Also, now that the header is found, I get this error:

CMakeFiles/Simple.dir/Simple.cxx.o:(.data+0x34): undefined reference
to `itk::MRCImageIOFactoryRegister__Private()'

with this very simple code:

#include "itkImage.h"
#include "itkImageFileReader.h"
#include "itkRescaleIntensityImageFilter.h"

int main(int argc, char *argv[])
{

  typedef itk::Image<unsigned char, 2>  ImageType;

  typedef itk::ImageFileReader<ImageType> ReaderType;
  ReaderType::Pointer reader = ReaderType::New();
  reader->SetFileName(argv[1]);

  typedef itk::RescaleIntensityImageFilter< ImageType, ImageType >
RescaleFilterType;
  RescaleFilterType::Pointer rescaleFilter = RescaleFilterType::New();
  rescaleFilter->SetInput(reader->GetOutput());
  rescaleFilter->SetOutputMinimum(0);
  rescaleFilter->SetOutputMaximum(255);

  return EXIT_SUCCESS;
}

Any thoughts on that one?
