[Xavier Delannoy]

my CMakeLists.txt need an environement variable. 

I try this, with no success.
/tmp> cat CMakeLists.txt 
IF(DEFINED ENV{TEST})
        MESSAGE("test is defined")
ELSE(DEFINED ENV{TEST})
        MESSAGE("test is not defined")
ENDIF(DEFINED ENV{TEST})

/tmp>env | grep TEST
TEST=toto

/tmp cmake .
test is not defined
-- Configuring done
-- Generating done
-- Build files have been written to: /tmp

I try with REQUIRED_VARIABLE, with no success too.

help ;)

regards
