Quoting Horacio Sanson <[EMAIL PROTECTED]>:
Either you have not re-run CMake or your CMake is broken. Did you
install it from Ubuntu packages?

Good idea, but I believe you would also need the following modification to
the above logic
find_library( SCTP_LIBRARY sctp )
if(SCTP_LIBRARY)
target_link_libraries( your_exec ${SCTP_LIBRARY} )
endif(SCTP_LIBRARY)
Running this CMake script gives me:
CMake Error: Error required internal CMake variable not set, cmake may
be not be built correctly.
Missing variable is:
CMAKE_FIND_LIBRARY_PREFIXES
I have cmake from Kubuntu Hardy Heron installed.

The reason for the extra logic is that if libsctp is not found then
SCTP_LIBRARY with be set to "SCTP_LIBRARY-NOTFOUND" which would screw up
"target_link_libraries" without the "if" protection.
