vst Spleeter: A VST interface to Spleeter

Note: This project has only been tested on OSx 10.14 and 10.15

This project is uses JUCE and spleeterpp to make a simple application that runs spleeter in c++.

Credit for most of this work goes to https://github.com/gvne.

Optional: download and install Intel's math kernel library. If you do not install it, leave out the Drtff_use_mkl=ON cmake flag and remove the mlk libraries from externalLibraries in the jucer file.
Download and install JUCE
On MacOS, install xcode. On Win, install Visual Studio 2017.
On Win, install git-bash.
git clone https://github.com/diracdeltas/spleeterpp.git && cd spleeterpp
In bash or git-bash, set SPLEETERPP_INSTALL_DIR=$(pwd)/install
Install anaconda from https://docs.anaconda.com/anaconda/install/. On Windows, make sure that conda is in your path and the Python version that comes with Conda precedes the regular system Python in your path (make sure ~/anaconda3 is first in the path and ~/anaconda3/Scripts is also in the path).

on macOS: mkdir build && cd build && cmake -GXcode -Drtff_use_mkl=ON -DCMAKE_INSTALL_PREFIX=$SPLEETERPP_INSTALL_DIR ... on windows, replace Xcode with ""Visual Studio 15 2017 Win64"
run cmake --build . --target install --config Release. on MacOS, this may fail if Tensorflow wasn't correctly downloaded. to fix, delete the (NOT tensorflow_lib OR NOT tensorflow_framework_lib) condition from cmake/add_tensorflow.cmake, then run step 1 again.
in another folder, do git clone https://github.com/diracdeltas/vstSpleeter.git && cd vstSpleeter. on Windows, also do git checkout feature/windows
bash configure.sh $SPLEETERPP_INSTALL_DIR
open the .jucer file in projucer and click on the VS2017 or xcode icon to open in your IDE.
build the targets in your IDE, making sure that the scheme is set to Release.
on windows, copy extras/tensorflow.dll to %SystemRoot%\system32 (you may need to open File Explorer as administrator to do this), then run postbuild.sh to package the vst3.
