Quoting Horacio Sanson <[EMAIL PROTECTED]>:
Indeed.
If you place the PROJECT directive at the top of your CMakeLists.txt,
or remove the PROJECT directive, it works fine. But if you place the
PROJECT directive where you've put it, it complains.
Given that cmake --help PROJECT does not say anything about placing
PROJECT at the top of the CMakeList.txt, this is either a bug with the
CMake docs or a bug in the PROJECT command.
By the way, CMake 2.4.8 packages for Gutsy are available in my PPA:

Either you have not re-run CMake or your CMake is broken. Did you install
it from Ubuntu packages?
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)

Most probably a bug in the Ubuntu package?? Will
