You are not missing anything, simply you are wrongly using the IF
construct because the second command should be ELSE, not ELSEIF.
Your construct can be interpreted like this one
IF(ZLIB_FOUND)
MESSAGE( WARNING "HAVE system zlib" )
ELSE(ZLIB_FOUND)
IF(ZLIB_FOUND)
MESSAGE( WARNING "NO system zlib" )
ENDIF(ZLIB_FOUND)
ENDIF(ZLIB_FOUND)
so, of course you get no output if zlib is not found, and two outputs if
zlib is found.
The right construct is
IF(ZLIB_FOUND)
MESSAGE( WARNING "HAVE system zlib" )
ELSE(ZLIB_FOUND)
MESSAGE( WARNING "NO system zlib" )
ENDIF(ZLIB_FOUND)
Bye
