Add information on how to build the plugin

[ycollet]

I am trying to build CMBNEX on Fedora.
I downloaded vst3sdk but it looks like the version of vst3sdk is important to build the plugin.
Add some information on how to build the plugin:

• vst3sdk version
• where to install the vst3sdk
• how to setup the build.

First of all, this project was not really meant to be built by anyone, it's public so I can host the VST3 download and the manual here.

The folder structure should be like

• Parent folder
  • VST_SDK/
    • vst3sdk/
  • CMBNEX/
    • CMakeLists.txt

I am pretty sure VST SDK version does not matter, just download the latest from here https://www.steinberg.net/developers/ and put the contents of the zip file in VST_SDK.

Also, I am not sure if it'll even build on Linux. Let me know how it goes

OK, thanks for these information, I will keep you informed :)

The setup:

mkdir CMBNEX
cd CMBNEX/
mkdir VST_SDK
cd VST_SDK/
git clone https://github.com/steinbergmedia/vst3sdk
cd vst3sdk/
git checkout v3.7.11_build_10
git submodule update --init --recursive
cd ../..
git clone https://github.com/KaixoCode/CMBNEX
cd CMBNEX/
mkdir build
cd build/
cmake -DCMAKE_CXX_FLAGS=RELEASE ..

The first error I met:

CMake Error at /home/collette/tmp/CMBNEX/VST_SDK/vst3sdk/cmake/modules/SMTG_AddSMTGLibrary.cmake:224 (message):
  [SMTG] PROJECT_VERSION is not defined for target: "CMBNEX".  To fix this,
  set the VERSION option of the most recent call of the cmake project()
  command e.g.  project(myPlugin VERSION 1.0.0)

In CMakeLists.txt, I added:

project(${PRJ_NAME} VERSION 1.0.0)

And then some problems related to vst3 sdk pop up:
