Re: [cmake-developers] custom_command rebuild output file when depend files change?
Are these absolute paths?
Yes. All absolute file paths.
Where is the output file referenced? It needs to be in a target somewhere.
Forgot to mention, we also do this after:
set_source_files_properties(${OUTPUT_FILE} PROPERTIES GENERATED 1)
list(APPEND SOURCE_FILES ${OUTPUT_FILE})
[...]
add_library(${PROJECT_NAME} STATIC ${SOURCE_FILES})

Yes, it should. This is well tested.
DEPENDS ${INPUT_FILES}

OUTPUT ${OUTPUT_FILE}

That shouldn't be necessary. add_custom_command does that for you.
list(APPEND SOURCE_FILES ${OUTPUT_FILE})
[...]
add_library(${PROJECT_NAME} STATIC ${SOURCE_FILES})
Please post a complete example.
Thanks,

Re: [cmake-developers] custom_command rebuild output file when depend files change?
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. However it does not mention that
setting that property ourselves prevents the dependencies from functioning
correctly. Perhaps it's a bug, I don't know.
But now it works, thanks for the pointer Brad !
