I tried to symlink lazbuild into $HOME/bin and then inside the project dir I
tried this:

$ lazbuild videosplitcmb.lpi
Error: (lazarus) invalid Lazarus directory "": directory lcl not found
Error: (lazarus) Building failed: videosplitcmb.lpi

I tried lazbuild --help and found out that there is an option one can enter too:

lazbuild --lazarusdir=/home/bosse/dev/lazarus/2.2.4 videosplitcmb.lpi

And this time it worked fine!
I now have the modified tool and I moved it to the Ubuntu Server where it works
just fine.

Thanks for the instruction on how to do it.
