[CMake] IF( ${VAR} ) behaviour

[Fernando Cacciola]

Hi people,

Consider the following (tested in 2.4.7):

set ( VAR "whatever" )

message( STATUS "VAR=${VAR}" )

if   ( ${VAR} )
  message( STATUS "VAR evaluates to true" )
else ( ${VAR} )
  message( STATUS "VAR evaluates to false" )
endif( ${VAR} )


it prints "VAR evaluates to false".

Is that expected??  The documentation of IF() doesn't match this behaviour 
AFAICS.

TIA
