[CMake] Batch converting several files

[Martin Fischer]

Hi Andy,

it seems I don't understand the direction you are pointing me to.  I 
used add_custom_command in some occasions. So now I tried:

FOREACH( FILE ${SOURCEFILES})
          ADD_CUSTOM_COMMAND ${FILE}.out
              COMMAND ${tool_EXE} ${CMAKE_CURRENT_SOURCE_DIR}/${FILE}.in 
${CMAKE_CURRENT_BINARY_DIR}/${FILE}.out
	     DEPEND tool ${FILE}.in
        )
ENDFOREACH( FILE )

CMake outputs: "Wrong syntax. Unknown type of argument"

It looks like I'll go the less flexible way to code a list of commands 
to execute.

Frustrated
Martin
