Actually, there are 2 differently licensed libcacard code bases, there is
the standalone libcacard which you are referring to and which is indeed
GPLv3, but there's also a libcacard included in qemu, which will be used in
the future, and which is licensed as LGPLv2.1 or later according to the
header in each source file.
We really should get rid of the standalone libcacard, this would clear up
this kind of confusions ;) At the very least, I think we can change the
GPLv3 to the more permissive LGPLv2.1+ since both code bases have the same
origin.
