compile with libsysfs2

I'm compiling libchipcard 1.9.16 alpha against libsysfs2 and get this error

make[5]: Entering directory

`/root/libchipcard/libchipcard2-1.9.15.99+1.9.16alpha/src/drivers/ctapi'
/bin/sh ../../../libtool --tag=CC --mode=link cc  -g -Wall -O2   -o
ctapi  driverctapi.o readerctapi.o main.o
../../lib/chipcard2-server/driver/libchipcard2d.la -L/usr/lib
-lgwenhywfar -L/usr/lib -lusb -lsysfs

cc -g -Wall -O2 -o .libs/ctapi driverctapi.o readerctapi.o main.o
../../lib/chipcard2-server/driver/.libs/libchipcard2d.so -L/usr/lib
/usr/lib/libgwenhywfar.so /usr/lib/libusb.so /lib/libsysfs.so
../../lib/chipcard2-server/driver/.libs/libchipcard2d.so: undefined
reference to `sysfs_open_device_tree'

Any way around?
