## Link to GitHub Issue, if one exists
n/a

## Description of change
Add CMake option to disable SCard functionality. Needed by some builds
of WINE, where distributor opted to not enable scard functionality for
whatever reason

## Testing
Building with `cmake -DWITH_SCARD=OFF` does not link against winscard
Building without this option at all links against winscard
