Installing from source ./configure can't find texlive
I'm trying to install SageMath from source on Ubuntu 20.04. ./configure says, among other things that are less a concern to me:
Checking whether SageMath should install SPKG texlive...
checking for pdflatex... /usr/local/texlive/2022/bin/x86_64-linux/pdflatex

configure: no suitable system package found for SPKG texlive
I always install the latest version of texlive, and ./configure does indeed find pdflatex, as you see. All the packages are there, I use some of them all the time and I keep my installation updated frequently. The $PATH is set up as per the instructions of texlive. I really wouldn't like Sage to install another texlive in my system because that will break things.
Is there any way I can tell ./configure where to find those packages?
Sage will not install another texlive. The sentence "Checking whether SageMath should install SPKG texlive" is a generic sentence which does not make sense here, because texlive is a dummy package (its spkg-install is empty). It is there only to give suggestions on how to install it at the end of the configure log depending on the operating system.
