Summary:                    FortranCInterface.cmake does not pass
CMAKE_BUILD_TYPE flags
Description: 
In attempting to compile a mixed language static Windows executable,
FortranCInterface.cmake breaks the cmake configuration.

Windows MSVC and Intel compilers toggle between static and dynamic
system/compiler libraries using /MT and /MD compiler flags respectively.
/libs:static /threads and /libs:dll /threads are equivalent to /MT and /MD
respectively.

The issues stems from a difference in initialization across C/CXX flags and
Fortran flags. The static/dynamic flags are initialized in the base
CMAKE_Fortran_FLAGS while they are initialized in the
CMAKE_[C|CXX}_FLAGS_<CMAKE_BUILD_TYPE> flags. 

FortranCInterface.cmake does not pass the BUILD_TYPE flags through to the
subproject. This results in mixed dynamic and static libraries and multiply
defined symbols at linking.


Steps to Reproduce: 
1) Create cmake configuration which utilizes FortranCInterface.
2) Use Intel compilers on Windows
3) Add these additional configuration options to a configuration script.bat:
 cmake ^
-D CMAKE_C_FLAGS:STRING="/DWIN32 /D_WINDOWS /W3 /Zm1000" ^
-D CMAKE_CXX_FLAGS:STRING="/DWIN32 /D_WINDOWS /W3 /Zm1000 /EHsc /GR" ^
-D CMAKE_Fortran_FLAGS:STRING="/W1 /nologo /fpp" ^
-D CMAKE_C_FLAGS_RELEASE:STRING="/D_NDEBUG /O2 /MT" ^
-D CMAKE_CXX_FLAGS_RELEASE:STRING="/DNDEBUG /O2 /MT" ^
-D CMAKE_Fortran_FLAGS_RELEASE:STRING="/D_NDEBUG /O2 /MT" ^
-D CMAKE_Fortran_COMPILER:STRING=ifort ^
-D CMAKE_CXX_COMPILER:STRING=icl ^
-D CMAKE_C_COMPILER:STRING=icl ^
-G "NMake Makefiles" ^
%*

4) initialize Intel development environment
5) run script.bat path/to/src

Additional Information: 
This could be fixed by standardizing the initialization of compiler flags across
all languages or passing all compiler flags through to the FortranCInterface
subproject.

This prevents a static Windows build for executable deployment.
It would be convenient to have this fixed as soon as possible.
