xilink always forcing rebuild (change in the command line)

Hello,

I am using Intel Composer XE SP1 Update 4 for Windows.
To compile my project, I use :

call "%VS110COMNTOOLS%vsvars32.bat"
msbuild /v:d /p:VisualStudioVersion=11.0;Configuration=Release Marvel.Maths.AvxCalculationNativeKernels.vcxproj

• vsvars32.bat : configure env for VS2012 (I also have VS2010 & VS2013 on my desktop)
• VisualStudioVersion=11.0 : ensure Visual Studio 2012 env is configured (cf. http://blogs.msdn.com/b/webdev/archive/2012/08/22/visual-studio-project-...)

With this setup, if I run msbuild command again, xilink is called :

  All outputs are up-to-date.
  Forcing rebuild of all source files due to a change in the command line since the last build.
  Forcing rebuild of all source files due to a change in the command line since the last build.

(full detailed log is attached)
I cannot find any difference between both command lines (starting from the /OUT parameter)

Why is xilink rebuiling my project?

Thanks in advance for your help
