Comment:
I had to zap my xbps-src dir earlier so this recomp is taking longer than expected. If you want to test the below do it and let me know if it works, I'll confirm on my side:

```
pkgname=steinberg-vst
version=3.6.14
revision=3
short_desc="Steinberg's VST SDK (version 3.6)"
homepage="https://www.steinberg.net/sdk_downloads/"
hostmakedepends="unzip"
maintainer="lane-brain <lane@mailbox.org>"
_sdkarchive="vst-sdk_3.6.14_build-24_2019-11-29.zip"
distfiles="https://download.steinberg.net/sdk_downloads/${_sdkarchive}"
wrksrc=${pkgname}-${version}
license="custom:Steinberg"
checksum=1f61d847d4fbd570a2b3d3cc14210b4e7f808f87b641a44b146a07f708cb1552
repository=nonfree

do_extract() {
    unzip ${XBPS_SRCDISTDIR}/${pkgname}-${version}/${_sdkarchive}
    echo $PWD
}

pre_install() {
    cd ${wrksrc}/VST_SDK
    cp -r VST2_SDK/* VST3_SDK
    echo $PWD
}

do_install() {
  # install headers
    echo "do_install: $PWD"
    vst_sdk_path="${wrksrc}/VST_SDK/VST3_SDK/public.sdk/source"
    header_path="usr/include/vst36"

    mkdir -p ${DESTDIR}/${header_path}
    #cd ${wrksrc}/${header_path}
    vcopy ${vst_sdk_path} ${header_path}

    mkdir -p ${DESTDIR}/${header_path}/pluginterfaces/vst
    vcopy ${vst_sdk_path}/../../pluginterfaces/vst ${header_path}/pluginterfaces/vst
}

post_install() {
    vlicense ${wrksrc}/VST_SDK/VST3_SDK/LICENSE.txt
}
```
