Hi Brad,
You need the custom command to run every time the build starts:
...
copy-if-different check. The key is then to make the library depend on this rule at a *target* level, but only on version.h at a *file* level.
Because such a custom target is "always considered out of date", the library that depends on it is also considered out of date and would be rebuilt, even though no source code changed. Assembling our 100+ object files into a large library is fast on Linux but dead slow on Windows/Cygwin. At least it is much slower than reading and comparing the timestamps of the 100+ files (no, disabling the virus scanner didn't help much;)
From the fact that it is possible and simple to define library targets that
depend on object files that depend on source code that depend on header files, I hoped that it would be just easy to have arbitrary other targets depend on similarly complex input (in my case: the same minus one file). I put some hope in the "output_required_files()" command but it always outputs nil.
