Qwt build error in VS2015

I am getting the following error:
C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V140\Microsoft.Cp pBuild.targets(1189,5): warning MSB8012: TargetPath(D:\DAN\QWT\QwtPjts\SimplePlot\SimplePlo t\debug\Simple.exe) does not match the Linker's OutputFile property value (D:\DAN\QWT\QwtPjts\SimplePlot\SimplePlot\debug\Si mplePlot.exe). This may cause your project to build incorrectly. To correct this, please make sure that $(OutDir), $(TargetName) and $(TargetExt) property values match the value specified in %(Link.OutputFile).
