docs do not build
cmake 22.3 gcc 9.3 linux 20.04 all deps satisfied
cmake does not build /doc
Building docs is tricky because in order to do it we usually need to install newer versions of breathe and sphinx that in the distribution. They contain necessary bug fixes.
Currently, we use ubuntu 20.04 to build the docs, i.e.
https://jenkins.esss.dk/dm/blue/organizations/jenkins/ess-dmsc%2Fh5cpp/detail/master/348/pipeline/570
which gives us
https://ess-dmsc.github.io/h5cpp/latest/index.html
but we install breathe and sphinx with pip

On debian11 make html works with packages given it the distribution.
Could you show us the error you get when you build the documentation then we can help you more.
Thank you very much; in my setup it had to be installed system wide as root, sudo make html had to be used output ended up in builld/Release/doc/build, system wide installation is still obsure to me ...
