Subject: [PATCH] isabelle: fix vampire build

* Add install to Cmake now that latest version has it
* Add move because isabelle needs the binary to be 'vampire'
* Add flag to ignore search for Z3, it doesn't work and isn't required
* Change build to only use gcc14 on linux, on darwin clang21 is fine
