I think what CE ment was static v.s. dynamic lib names, but what you write 
is true as well, the library has different names on different OS-es/archs, 
I am not even sure NDI stuff builds for windows, I always tested linux 
only.

With dynamic loading we can rely on the library name defined in the NDI 
SDK headers which should be the proper one for each OS/arch.
