[IGSTK-Developers] Linking error related to IGSTK

[Zein Salah]

Dear all,

A project of mine is based on

IGSTK 4.4
VTK 5.2.1
Qt 4.8.2

under Windows 7, Cmake 2.8.9, Visual Studio 2008.

All toolkits built and compiled error-free, for both release and debug.

When compiled my own project, I got the error below:

1>------ Build started: Project: ArMicroscope, Configuration: Release

What does this error mean? how to get around it?

Many thanks,
