Summary0014777: OBJECT libraries cause Fortran to relink each time
DescriptionWhen using the Visual Studio 10 generator and the solution includes a Fortran executable using objects from a C[XX] OBJECT library, the executable will relink each time 'Build solution' is run (or the executable's project is built).

It ceases to happen when the object files are manually removed from the project as sources and instead added as additional linker dependencies. CMake should probably take this approach when generating a vfproj.

I believe the same was happening for me in VS 2005, but I no longer have that on hand for testing. Neither do I have a chance to test this on newer Visual Studios.

Using "Intel(R) Visual Fortran Compiler XE 13.0.1.119"
Steps To ReproduceExpand the attached testcase and run

> cmake -G "Visual Studio 10"

It looks like we already have the same workaround for a different problem in VS 7.1 and below. We can re-use the code supporting that for this case too:

 VS: For Intel Fortran .vfproj put OBJECT libs in link line

Sounds great, thanks for such a quick solution. I will only be able to test it using 'next' on Monday, but I will definitely do so.
