cmake: read and compile dynamically-generated list of cpp files

Question

I have a custom tool that processes a given list of IDL files and produces a number of .cpp and .h files as output. I want to add those files to the list of things to compil

Answer 1

This is a few years late but this works just fine:

#run whatever tool that generates the cpp files
execute_process(COMMAND "./your_tool.sh")

#read files from files.txt and make a cmake 'list' out of them
file(READ "files.txt" SOURCES)

#found this technique to build the cmake list here:
#http://public.kitware.com/pipermail/cmake/2007-May/014236.html
#maybe there is a better way...
STRING(REGEX REPLACE ";" "\\\\;" SOURCES "${SOURCES}")
STRING(REGEX REPLACE "\n" ";" SOURCES "${SOURCES}")

#at this point you have your source files inside ${SOURCES}
#build a static library...?
add_library(mylib STATIC ${SOURCES})
