Still a work-in-progress. Nothing to see here yet.
First, install CMake and a generator (like Ninja).
Clone the project with submodules:
git clone --recurse-submodules https://github.com/carlthome/ml-vst
Then generate a project and build it.
# Generate a build project (with e.g. Ninja).
mkdir build && cd build
cmake -S=.. -B=. -G=Ninja --fresh
# Build project.
cmake --build .
