[makefile] Update supercollider to v3.12

[SteveRussell33]

Updates supercollider to v3.12 instead of using old vcv-prototype-support branch.
Fixes#54 (comment)

Nice, make dep works now. But I'm still getting an error while building the plugin with make:

Do I have to install Boost via pacman, maybe?

[clwe]

Installing Boost via pacman works:
pacman -S mingw-w64-x86_64-boost
So that builds successfully. But maybe we should include the Boost header directory via the build command, since it's already "bundled" within the supercollider build directory?

[clwe]

Some other obseravtions:

• On my machine the generated supercollider library is called liblibsclang.a and resides in dep/supercollider/build/lang/liblibsclang.a.
• The HIDAPI Library is in dep/supercollider/build/external_libraries/hidapi/windows/libhidapi.a.

So make fails to recognize that the library was already built and tries to rebuild it, which fails, because the build folder is already there.

Related: #52 (comment)

I just read your other #54 (comment) about the boost headers. That helped! I think we can also add -Idep/supercollider/external_libraries/boost/ to the FLAGS variable to use the boost that is used to build libsclang.a.

While that resolves the error in #59 (comment), (so boost/filesystem works) it throws new errors about the flags -lasound and -ludev. I guess they are part of the full boost package when I install it with pacman, but maybe they are not part of the built-in boost?

So when compiling with FLAGS += ... -Idep/supercollider/external_libraries/boost/ I'm getting this right now:

$ make

collect2.exe: error: ld returned 1 exit status
make: *** [../Rack-SDK-1.1.6//compile.mk:59: plugin.dll] Error 1

When I remove those flags, I get linker errors, so I guess those libraries are really needed.

What I can tell from my cursory searches is that asound is a linux package related to Advanced Linux Sound Architecture (ALSA).
dep\supercollider\external_libraries\portaudio\portaudio_submodule\CMakeLists.txt line 314

udev is another Linux package "libudev-dev" needed by hidapi test program (remove?)
