What I'm doing now is to invoke cmake from the command that builds the
script:
add_custom_command(OUTPUT ${LLVM_CONFIG}
COMMAND <... builds the script ...>
COMMAND cd ${LLVM_BINARY_DIR} &&
${CMAKE_COMMAND} -U HAVE_LLVM_CONFIG ${LLVM_MAIN_SRC_DIR}
DEPENDS ...
)
where HAVE_LLVM_CONFIG is the variable that says if the script exists.
This works, at least on MSYS/MinGW, and it is simpler than splitting the
project.

This is very much appreciated, Brad. I have experience dealing with you
long time ago with gcc-xml and seeing your name related to CMake was one
of the main reasons for choosing it.
Thanks,
