macOS Monterey x86_64 compilation error

Hello. I trying to compile v2 branch. Getting this error after make dep:

Just learned through this issue that there is a v2 branch. Is there an official process how the compatibility to v2 is implemented, who is in charge and what are the changes? @AndrewBelt we need some guidance.

I was able to build so far on the v2 branch (on a M1 Mac, Monterey, compiling for x86_64) with just the Faust and LuaJIT script engines. However, I get an error within Rack2 that says No engine found for ..dsp extension (and the same for .lua when I try to load lua scripts).

EDIT: Found the bug. The V2 SDK's system::getExtension returns the leading . (as it uses std::filesystem::path::extension under the hood) whereas V1's string::filenameExtension doesn't.

f693e76 doesn't account for this change, which is why the error message shows two periods.

(I wonder if the change in semantics in the SDK was intentional? Anyways, the std::filesystem::path behavior does seem to make more sense.)
