Hello every body,

I faced with error LNK 1181, when i try to build the Light Weight Robot IGT module on Slicer with visual studio 2015 update 3.

Error LNK1181 cannot open input file ‘vtkSlicerOpenIGTLinkIFModuleMRML.lib’ vtkSlicerLightWeightRobotIGTModuleMRML E:\LightWeightRobotIGT\B\LightWeightRobotIGT\MRML\LINK 1

I would be so appreciated if anyone could help me to fix the error.
