[CMake] linking static vs dynamic

[Yngve Inntjore Levinsen]

If you want everything linked statically I believe you can use the variable, BUILD_SHARED_LIBS, something like
OPTION( BUILD_SHARED_LIBS "Set to OFF to build static libraries"  OFF )
I do believe it will still use dynamic libraries if static aren't available, but I am unsure about that part.

Cheers,
Yngve
