Fail to build

[hfiguiere]

When building the top-level workspace (with a simple cargo build), on Linux, I get the following error:

error: multiple packages link to native library `alsa`, but a native library can be linked only once

package `alsa-sys v0.1.2`
    ... which is depended on by `alsa v0.2.2`
    ... which is depended on by `midir v0.5.0`
    ... which is depended on by `nannou_apps v0.1.0 (/home/hub/source/oscen/nannou-apps)`
links to native library `alsa`

package `alsa-sys v0.3.0`
    ... which is depended on by `alsa v0.4.2`
    ... which is depended on by `cpal v0.12.1`
    ... which is depended on by `cpal-apps v0.1.0 (/home/hub/source/oscen/cpal-apps)`

cpal-apps shall downgrade cpal to 0.11.
Otherwise midir 0.7.0 should work, but nannou-audio still pull cpal 0.11.
