How to generate the exe file ? (run in windows) #88

Hi, I successfully run the source code in ubuntu and generate the file in floder 'opt' by using the update_openEMS.sh file, but I don't know how to generate the exe file that can run in the windows.

The windows build is a very long and complicated one. Please just download the prebuild binaries from openEMS.de

An easy route is MinGW / MSYS2. If there's a need for testing the latest development code, one can use MinGW to build openEMS on Windows in a way that is almost identical to Unix. Performance should be similar to MSVC, since MinGW uses the same GCC to generate x86_64 code as a native PE binary, it's not an emulation.

I also managed to cross-compile openEMS to Windows from ArchLinux via MinGW, then openEMS can be run under Wine (ArchLinux was used because it contains many user packages for MinGW cross-compile, such as Boost or VTK). It means that one can debug and test openEMS's Windows-specific code completely on GNU/Linux without ever touching Windows or MSVC, very useful for development.

I'll soon document the procedures at GitHub Discussion.
