Linking error on linux #61

I get the following linking error when trying to build ORCA-C:

/usr/lib/gcc/x86_64-pc-linux-gnu/9.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: /tmp/orca.77MRyA.ltrans0.ltrans.o: undefined reference to symbol 'keypad'
/usr/lib/gcc/x86_64-pc-linux-gnu/9.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: /lib64/libtinfow.so.6: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status

This can be solved by linking against tinfow:
