Removing the line set_source_files_properties(${OUTPUT_FILE} PROPERTIES GENERATED 1)
...fixed it. Indeed the documentation says "Each output file will be marked with the GENERATED source file property automatically".

But now it works, thanks for the pointer Brad ! -----Original Message----- From: Brad King [mailto:brad.k...@kitware.com] Sent: Monday, June 1, 2015 2:11 PM To: Robert Goulet Cc: cmake-developers@cmake.org Subject: Re: [cmake-developers] custom_command rebuild output file when depend files change?
