This is likely due to commit v3.9.0-rc1~144^2~1:
```
FortranCInt: Pass CONFIG flags to try_compile
This change ensures that Intel Fortran's /libs: in
CMAKE_Fortran_FLAGS and Visual C++'s /MT or /MD in the
CMAKE_C_FLAGS_RELEASE do not conflict with each other.
```
With that change I'm able to reproduce the failure with
VS 2013 and Intel 2016:
```
cmake_minimum_required (VERSION 3.7)
project(Test C Fortran)
string(REPLACE "/MD" "/MT" CMAKE_C_FLAGS_RELEASE "${CMAKE_C_FLAGS_RELEASE}")
include(FortranCInterface)
FortranCInterface_VERIFY()
```
If the project is changing the C and C++ flags to use a static
runtime library, it should do that for Fortran too:
```
string(REPLACE "/libs:dll" "/libs:static" CMAKE_Fortran_FLAGS
"${CMAKE_Fortran_FLAGS}")
```
Adding that line fixes the problem for me.
