I'm trying to build from git-20200909 on Linux.
I have theses basic dependencies installed:

crossguid, flatbuffers, libfmt, libspdlog, wayland-protocols, wayland

Issuing this command yields an error that Python3 (>= 3.5) is not found. I have Python-3.7.2 library provided by my distro.

Code:
$ sudo cmake /tmp/kodi-git20200909 -DCMAKE_INSTALL_PREFIX=/usr -DX11_RENDER_SYSTEM=gl -DCMAKE_BUILD_TYPE=Release -DENABLE_MDNS=OFF

Is this error spuriously related to this:

Code:
-- include/linux/udmabuf.h not found

-- include/linux/dma-heap.h not found

-- include/linux/dma-buf.h not found

These Linux headers are anything but in the include/linux directory. They are scattered around in include/, for example include/uapi/linux. Building against Linux 5.4.60.

Likely missing dev package. python3-dev(el) on debian/redhat derivates.

Could you give me a filename in this package? I'll check to see if I can find it on my system. If i'm able to find it that means that I also have the 'dev' part of the package installed. I think I might already do.

/usr/bin/python3-config <- that one is provided by python3-dev which installs plenty of dependencies. Please check the manual of your distribution.

Thanks, I already have this file installed. All the corresponding dev files are clearly installed.

Jep - you are right
