Update ABSL to tip

[carlocab]

This should hopefully fix the failing build.

Nope, this doesn't work:

The call site seems fine:

bloaty/src/bloaty.cc

Lines 181 to 182 in 6b78e08

	if (absl::debugging_internal::Demangle(demangle_from.data(), demangled,
	sizeof(demangled))) {

So I suspect we just need to link the right absl library.

[haberman]

Is it possible that we're just missing a lib in the list of libs here?

bloaty/CMakeLists.txt

Lines 313 to 315 in 6b78e08

	list(APPEND LIBBLOATY_LIBS absl::strings)
	list(APPEND LIBBLOATY_LIBS absl::optional)
	list(APPEND LIBBLOATY_LIBS Threads::Threads)

[carlocab]

Yes, I think so. Added absl::demangle_internal to the list of libraries that need to be linked.

Edit: nope, that error was just from picking up a separate Abseil install on my system. This PR builds fine for me now. Please have a look, @haberman.

[carlocab]

Note that the update to Abseil is not needed to fix anything, but I kept it anyway since it doesn't seem to hurt. Happy to back out that change if needed.

[carlocab]

Windows is still broken, but everything else seems to work now.

Don't know anything about Windows unfortunately. I'll try to dig into it tomorrow.

I also wonder if dropping the Abseil update and keeping only the change to CMakeLists.txt will be enough to fix Windows.

[Oyyko]

Only Adding list(APPEND LIBBLOATY_LIBS absl::demangle_internal) works for me (Ubuntu 20.04 x86-64). Thanks!

[carlocab]

Windows CI should be good at #385.

[carlocab]

Looks like #385 worked.

Would still be nice to update Abseil to tip anyway, but I'm not sure how to fix the Windows errors...

[carlocab]

@haberman, this should be good to go too: https://github.com/carlocab/bloaty/actions/runs/10594891815
