   clang-tools-15, clang-tidy-15, clangd-15

and the build fails.

no, it is not. As said on IRC, there's a reproducer to build cvise 2.6.0-1 without the extra dependencies

I downloaded cvise, installed build-deps in a sid chroot
apt remove clang-tools-15 clang-tidy-15 clangd-15
dpkg-buildpackage -d
