Custom external script: I used a CUSTOM_COMMAND to execute a bash script to do it. I can send you the script if you are interested. I should have really written the external script in CMake and run it with Cmake -P ... but I couldn't figure out how to pass parameters when invoking the script. > Also, my generated headers sometimes > differs only by a C comment (a timestamp in fact), so do someone know if > there is a customizable way to compare files for uptodateness ? A dirty way would be to use something like awk to strip out the comment before comparing the files with diff. There is a tool called Metre [1] which does metric analysis of C files... in the readme the author said he used its engine as a basis to do a diff and the language level... its something I've wanted to look at but have been busy with other things... lexical diff of C opposed to source diff would be very useful to have.
