didkit build error

[cgair]

while I was building credible, following the steps in README, I had some problem running

make -C lib ../target/test/android.stamp
error:

// snip..
"-Wl,-Bdynamic" "-ldl" "-llog" "-lunwind" "-ldl" "-lm" "-lc" "-Wl,--eh-frame-hdr" "-Wl,-znoexecstack" "-L" "/home/uni01/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/i686-linux-android/lib" "-o" "/home/uni01/spruceid/didkit/target/i686-linux-android/release/deps/libdidkit.so" "-Wl,--gc-sections" "-shared" "-Wl,-zrelro,-znow" "-Wl,-O1" "-nodefaultlibs"
  = note: ld: error: unable to find library -lunwind

however I have libunwind installed on my system

libunwind.so
libunwind.so.8
libunwind.so.8.0.1
libunwind-x86_64.a
libunwind-x86_64.so
libunwind-x86_64.so.8
libunwind-x86_64.so.8.0.1

and about LD_LIBRARY_PATH:

/usr/lib/x86_64-linux-gnu

so what is going on and what i have missed?
