When dealing with ENV variable values, you should probably test their

Hi,
I'm trying to work out how to test for an environment variable in an IF
command, the following doesn't work:
SET(ENV{FOO} ON)
MESSAGE("FOO = $ENV{FOO}")# prints "FOO = ON"
IF(ENV{FOO})
MESSAGE("FOO is set")
ENDIF(ENV{FOO})
Does anyone know what the right syntax for doing this is, ple
