Builds fails against asio 1.34.0 due to io_service removal

[meanjollies]

asio 1.34.0 was recently released. Musikcube no longer builds successfully against it:

This appears to be due to the fact that io_service.hpp has been removed in 1.34.0 after being deprecated for some time.

Encountering this also while installing in Arch Linux.

Ravenports hit this as well. Is there an ETA to support the latest release of asio?

I have managed to overcome this on the AUR package by running git submodule init; git submodule update which clones src/3rdparty/asio and uses it
