Fuzztest installs antlr into the source folder #1898
Description
Discovered this while building fuzztest using cmake. In the root of my project a dist folder appeared with libantlr. This seems to be an outcome of this issue: antlr/antlr4#3784
Unfortunately antlr-cpp enables building tests by default, so fuzztest needs to explicitly turn off antlr-cpp building its own tests. (It should also disable building the shared library, since this is unused.)
I'd be happy to provide a PR, although I suppose I would have to sign the CLA first?
