Similar to issue 6102, but for libraries:

1. Build some program with RDMD
2. Modify a static library your program uses.
3. Run RDMD again.

RDMD will use the cached executable instead of rebuilding it.

I've made this a separate issue because it's more difficult to solve than issue 6102.

I assume the library is linked in via pragma(lib, "libname")?

Ultimately, for this to work correctly all the time, rdmd would need to know where the linker will look for library files. This isn't really realistic as it depends on the linker implementation (e.g. it might consult its own configuration files or environment variables). It's possible to add some heuristics to rdmd, though, e.g. to search /usr/lib, %LIB% / $LIBRARY_PATH, and the current directory.

I'm marking this as fixed, as a set of heuristics has been implemented in Git master.

If they don't adequately cover your use case, please open another more detailed bug report.
