I had a similar problem and also with a preprocessor. I ended up writing
a CMake script like this:
EXECUTE_PROCESS(
COMMAND my-command "${VAR_IFILE}"
RESULT_VARIABLE VAR_RESULT
OUTPUT_VARIABLE VAR_CONTENT)
# Do whatever you want with ${VAR_CONTENT}
FILE (WRITE "${VAR_OFILE}" "${VAR_CONTENT}")
UNSET(VAR_CONTENT)
and the in a CMakeLists.txt
# ADD_CUSTOM_COMMAND( ... ${CMAKE_COMMAND} -DVAR_IFILE=/path/to/source.m4.file
-DVAR_OFILE=/path/to/dest.cpp -P ${SCRIPT_ABOVE} ...)
# also SET_SOURCE_FILES_PROPERTIES and LIST(APPEND PRJ_SRCS "${VAR_OFILE}")

You could write a MACRO that will accept INPUT filename, OUTPUT filename
and a variable name for a list of sources (to completely automate
everything).
