libh2o-dev and libh2o-evloop-dev not available (yet?) in Debian trixie

[Gooseman42]

While trying to set up a trixie based Raspberry Pi and following the install instructions:

achim@galmon:~ $ sudo apt install protobuf-compiler libh2o-dev libcurl4-openssl-dev libssl-dev libprotobuf-dev \ libh2o-evloop-dev libwslay-dev libncurses5-dev libeigen3-dev libzstd-dev g++ libfmt-dev
Note, selecting 'libncurses-dev' instead of 'libncurses5-dev'
Error: Unable to locate package libh2o-dev
Error: Unable to locate package libh2o-evloop-dev

Is it equivalent if I compile from source (https://github.com/h2o/h2o) ?

Thanks!
Achim
