CMakeLists: do not enforce strict prototypes on Windows.

Browse Source 
On Windows, or at least when cross-built with Mingw-w64, build fails
because strict prototype fails on an included file (thus nothing we can
do about in json-c code):

> from /home/jehan/dev/src/json-c/json_util.c:44:
> /home/jehan/.local/share/crossroad/roads/w64/json-c/include/minwindef.h:196:3: error: function declaration isn't a prototype [-Werror=strict-prototypes]
>   196 |   typedef INT_PTR (WINAPI *FARPROC) ();

>       |   ^~~~~~~

Let's just disable the errors for Windows build.
