[CMake] XCode generator and flex

[Karl Merkley]

I got the latest cvs version of cmake to try out the XCode generator on 
my very complex project.   One of the first things I ran into was an 
error related to a custom flex command.

ADD_CUSTOM_COMMAND(OUTPUT ${WORDLISTS_BINARY_DIR}/wordlist.cpp
                    COMMAND flex
                    ARGS -L -o${WORDLISTS_BINARY_DIR}/wordlist.cpp
                         ${WORDLISTS_SOURCE_DIR}/wordlist.l
                    MAIN_DEPENDENCY ${WORDLISTS_SOURCE_DIR}/wordlist.l
                    )
XCode recognizes wordlist.l as a sourcecode.lex file.  XCode attempts 
to process this file but I don't end up with a wordlist.cpp output in 
the correct place.   I get a wordlist.yy.c as the generated file.

Is this just not implemented?  Any ideas on how to fix this?


    Thanks,
