[CMake] INSTALL CODE Error Results and Termination

[David Hauck]

Hello,

I've been using several "install (CODE "EXECUTE_PROCESS ...")" constructs in my top-level CMakeLists.txt file. However, I've been unable to capture/operate on any exit status of the embedded command. Unfortunately, documentation/searches haven't turned up any useful pointers. The closest I've come is a pointer in the following thread:
http://www.cmake.org/pipermail/cmake/2011-July/045475.html 
However, I've not been able to sufficiently read between the lines to get this working.

Does anyone have any thoughts on how to get something like the following working:

   install (CODE "EXECUTE_PROCESS (
      COMMAND ant ...
      WORKING_DIRECTORY ${PROJECT_SOURCE_DIR}/java
      ERROR_VARIABLE _err
   )
   If (${_err})
      MESSAGE( FATAL_ERROR \"err: ${_err}\")
   endif ()")

Thanks!
-David
