I found some references to this DLL, and it looks like greek to me. This is one comment I found about that dll:
Nope, the file (libiomp5mt.lib) is there, your install is either corrupted or you looked in the wrong folder -- folder hierarchy has changed with 11.0.
There is a workaround with specifying /nodefaultlib:libiomp5md.lib, and adding libiomp5mt.lib to the dependency list for each OpenMP project, architecture, and configuration but that is ugly, tedious and error-prone so I am not going to accept that.
Cheers,
Jim
