I have tried this in two separate systems with the same result: Hardy Heron (clean installation) with cmake 2.4-patch7 from Ubuntu repositories FreeBSD 7.1 with cmake 2.4-patch 7 from FreeBSD ports. In both cases running cmake causes an error about CMAKE_FIND_LIBRARY_PREFIXES missing. my CMakeLists.txt file : ######################################### EXEC_PROGRAM(uname OUTPUT_VARIABLE SYSTEM_NAME) SET(SYSTEM_NAME "${SYSTEM_NAME}" CACHE INTERNAL "") IF(SYSTEM_NAME STREQUAL "Linux") MESSAGE("LINUX BOX") LINK_LIBRARIES(sctp) ENDIF(SYSTEM_NAME STREQUAL "Linux") IF(SYSTEM_NAME STREQUAL "FreeBSD") MESSAGE("FREEBSD BOX") ENDIF(SYSTEM_NAME STREQUAL "FreeBSD") FIND_LIBRARY(SCTP_LIBRARY sctp) IF(SCTP_LIBRARY) MESSAGE("GOT SCTP LIBRARY") ENDIF(SCTP_LIBRARY) PROJECT(echo_demo) ADD_EXECUTABLE(echo_server echo_server.c) ADD_EXECUTABLE(echo_client echo_client.c) ########################################## regards, Horacio Most probably a bug in the Ubuntu package??
