trying to build VST UI for the first time, it gave me these errors:

@alfvy evidently, I've never tried building vst_window standalone on Windows; I've only ever tried building it as a dependency of a VST project.

Those should be enabled by the windef and winuser features on the winapi crate. Would you mind adding those to Cargo.toml and testing it out? If it works I'd be happy to accept a PR.

sorry for the long wait, I am in the middle of finals, the build failed and gave me the same errors, I did try building with Schwi's fork and it compiled flawlessly

also worth of note the plugin it self must implement the Send trait for it to be "thread safe"
