[Insight-users] itkImageFileReader: could not create IO object

[Matt McCormick]

Hi Marcos,

Please try using CMake with QtCreator.  Do "File -> Open Project..." and
select the top level project. CMakeLists.txt

See, e.g.

  http://doc.qt.digia.com/qtcreator-2.4/creator-project-cmake.html

HTH,
Matt
