This would be easier with wpa_supplicant 0.6.x which comes with an
example Makefile on how to build a library from the EAP peer
implementation.. Anyway, I would expect that 0.4.x can be made to work,
too, with some changes.

Did you build EAP-SIM code with PC/SC support? It looks like the
Makefile used in the IKEv2 project does not support this. Please take a
look at wpa_supplicant Makefile and CONFIG_PCSC option (you will need to
add -DPCSC_FUNCS to CFLAGS and link in pcsc_funcs.o and add -lpcsclite
to get the library in, too).
