Cannot install alsa-driver, INCLUDE_VERSION_H cannot be found

I am using Ubuntu 20.04. I want to upgrade my drivers as there is some problem with HDMI output. I tried to compile the alsa-driver package I downloaded from here. Here's the output when I run ./configure:

Please install the package with full kernel sources for your distribution
or use --with-kernel=dir option to specify another directory with kernel
sources (default is /lib/modules/5.8.0-63-generic/build).

What do I do?

TL;DR - Do not compile anything before reading current logs or adjusting some configurations.

Details are below.

If you are sure what are you trying to achieve - then you have to install all necessary development tools by

sudo apt-get install build-essential linux-headers-generic

then get build-dependencies for ALSA by enabling source code repositories (deb-src) in /etc/apt/sources.list manually by using Software and Updates (software-properties-gtk) and execution of

sudo apt-get build-dep alsa-driver

But please note that you are trying to compile nearly the same version 1.0.25+dfsg of alsa-driver which is already available in the official repository - see https://packages.ubuntu.com/source/focal/alsa-driver , you can get it by apt-get source alsa-driver. So after compilation you will not get any differences if you build the package with default configure options. Moreover sudo make install will make future system administration difficult, you should use checkinstall here or dpkg-buildpackage -uc -us. Probably you will add more mess than solve real problem.

So the better way to debug is finding actual bug in already installed deb-packaged version. You really can't guess where issue is - in kernel, in ALSA, in PulseAudio and so on.
