Both setupapi and dbghelp are part of visual studio environment and are
not necessary to be explicitly found.
However, this may cause other projects that want to build against iMSTK
to try to find these libraries. Since these packages may not have visual
studio environment setup at configure time, the find_package fails.
It's better instead to rely on them being automatically found during
compilation.
