Summary0008642: recompile of all files when adding one
Descriptionif one has

set(SRCS file1.c file2.c ...)
set_source_files_properties(${SRCS} PROPERTIES COMPILE_FLAGS -DUMMY)
add_library(test ${SRCS})

anytime I add a new file to the SRCS list, it recompiles all of them.
It only does this when I have the set_source_files_properties().
this is with the unix makefile generator.

I'd rather it only compile the one new file.

There is no good way to fix this. Each file depends on the flags.make file, and if you add a flag to one source file, then it will cause a rebuild. We tried a version with one file per object, but it created too many files on disk, and was too slow.
