install nlopt with intel fortran on windows

[hw666666]

I‘m trying to install NLopt with Intel fortran on windows but failed... I wonder are there any guidance?
Now I tried it as follows:

1. download “NLopt.v2.6.1.x86_64-w64-mingw32.tar.gz (64-bit)” on the "NLopt on Windows" page and extract it
2. add file "lib\libnlopt.dll.a" to “linker-input-Additional Dependencies” in Visual Studio.
3. copy file "lib\libnlopt.dll.a" and "include/nlopt.f" to the program directory.
4. Run the example program "t_fortran.f90"
   The program can debug successfully, but the ".exe" can't work because "libgcc_s_seh-1.dll" is lost in computer.
   Could you please tell me whether my installation progress is right and what I should do next?
   Thanks very much.
