Hi Niel,

Ok, there is no really good list of all variables. Unfortunately there
is no really good way of figuring out all the variables in CMake 1.6.

In 1.7 you can however probe for it. This is what SystemInformation test
does:

WRITE_FILE(${DumpInformation_BINARY_DIR}/AllVariables.txt "")

GET_CMAKE_PROPERTY(VARS VARIABLES)

FOREACH(var ${VARS})
  WRITE_FILE(${DumpInformation_BINARY_DIR}/AllVariables.txt 
             "${var} \"${${var}}\"" APPEND)
ENDFOREACH(var ${VARS})

Unfortunately GET_CMAKE_PROPERTY is the new feature and will not be
there until 1.8.

Just FYI, here are variables from 1.8 on CYGWIN machine:

If any of them looks useful, try it on 1.6 and you will see if it works.

I am affraid it will take a bit longer that 1 month.
Sorry.

You can always write an executable which will generate the list of files
and then call it from CMake. We do this kind of things in several
places.
