Back in January I got Sigil built on my Pop_OS box (With a lot of help--thanks again Kevin) and it has worked flawlessly, so I thought building the upgrade would be no problem. Silly me!

I went through the entire list of dependencies and checked they were there. All were at the latest level except I got these errors on the compat-dev ones (had a problem here back in January as I recall):

Spoiler:

chris@pop-os:~/sigil-build$ sudo apt-get install libqt6corecompat6-dev

Package qt6-5compat-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'qt6-5compat-dev' has no installation candidate
chris@pop-os:~/sigil-build$

But since the prior build worked, I tried cmake anyway, and got the following errors:

Spoiler:

Error from cmake:

I'll also attach the cmake logs.

Any help would be wonderful! TIA
