Oracle_fdw-0.9.9 make error: oci.h: No such file or directory

I try to install Oracle Foreign Data Wrapper but I get the following:

Description :
Instant
 Client allows you to run your applications without installing the 
standard Oracle client or having an ORACLE_HOME. OCI, OCCI, ODBC, and 
JDBC applications work without modification, while using significantly 
less disk space than before.  No recompile, no hassle.

This is the Basic package, supporting OCI, OCCI, and JDBC-OCI with all languages.
