Cannot compile due to missing header file

[cout]

I cannot compile master nor v0.7.22 due to this error:

Where can I find emunwaccessclient.h?

emunwaccess is a submodule. You'll have to pull that, e.g. using git submodule update --init --recursive.

@Skarsnik maybe we want to add a "full source" distribution (.tar.gz) to Releases -> Assets for future releases.

I see, I already had EmuNWAccess-qt under the top-level directory, but now the build scripts expect it under devices/EmuNWAccess-qt. I'm not sure how I got it into that state, but it builds successfully now.

In my defense, I did consider that it might be a submodule, but upon re-reading COMPILING.adoc, I thought "no, if QUsb2snes were using submodules, it would have been mentioned here". So it might be worth adding something there for clarity.
