[CMake] GET_CMAKE_PROPERTY not working ?!?

[Dekeyser, Kris]

Hi,
 
I have tried to use GET_CMAKE_PROPERTY to debug my CMakeLists.txt. I used
exactly the example in the book and placed the code at the end of the main
(root) CMakeLists.txt. I do get an output file, but it is always empty.
GET_CMAKE_PROPERY Seems to return an empty list in all cases. I have tried
the VARIABLES, CACHE_VARIABLES, COMMANDS and MACROS properties, but they are
all empty.
 
This is the code:
FILE(WRITE ${CMAKE_CURRENT_BINARY_DIR}/AllVariables.txt "")
GET_CMAKE_PROPERTY(VARS MACROS)
FILE(APPEND ${CMAKE_CURRENT_BINARY_DIR}/AllVariables.txt "${VARS}\n")
FOREACH(var ${VARS})
  FILE(APPEND ${CMAKE_CURRENT_BINARY_DIR}/AllVariables.txt "${var}
\"${${var}}\"\n")
ENDFOREACH(var)
What did I do wrong?
 
Regards, Kris
