[ITK-users] Unresolved external symbol

[Matt McCormick]

Hello,

It is recommended to use CMake CMakeLists.txt instead of Qt .pro files
to build your project.  You will have much less difficulty. Note that
QtCreator also supports CMake, and CMake has very good support for
working with Qt.

HTH,
Matt
