With the `ghc::filesystem` dependency from the previous commit. If we can replace the rest of the Boost.Filesystem dependency then we can get rid the one nasty runtime dependency we have, and it will make implementing the chainloading simpler since can reuse more code without bringing in Boost.

# Patch the VST3 SDK and replace all MSVC-isms so it can be compiled with
|
|
# winegcc. We do it this way instead of modifying the SDK directly so we don't
|
|
# have to fork multiple repositories and keep them up to date.
|
|
# If anyone knows a better way to get the SDK to compile with Win32 supports
|
|
# under winegcc without having to modify it then please let me know, because I'd
|
|
# rather not have to do this.

# patch-vst3-sdk.sh <sdk_directory>
