Proprietary Audio Plugins for Linux, but the right way

Why the current approach to VST and VST3 does not work for proprietary plugins on Linux ?

When building plugins for Linux there are two options and one problem:

Link to the system libraries
Build all your dependencies and statically link to them
Can't use gtk or qt.

Effective Modern CMake

Getting Started

For a brief user-level introduction to CMake, watch C++ Weekly, Episode 78, Intro to CMake by Jason Turner. LLVM’s CMake Primer provides a good high-level introduction to the CMake syntax. Go read it now.

After that, watch Mathieu Ropert’s CppCon 2017 talk Using Modern CMake Patterns to Enforce a Good Modular Design (slides). It provides a thorough explanation of what modern CMake is and why it is so much better than “old school” CMake. The modular design ideas in this talk are based on the book [Large-Scale C++ Software Design](https://www.amazon.de/Large-Scale-Soft

Freedrum on Linux

The recently released Freedrum has no official Linux support. But, fortunately, it uses standard Bluetooth LE MIDI. It doesn't seem to work out of the box, yet (on Ubuntu 17.04, most probably Ubuntu 18.04 will support it directly).

Bluez 5.46

One really needs bluez 5.46 or higher. On Ubuntu, these are packaged in artful proposed (amd64). Unfortunately, MIDI support is not enabled in this build (Ubuntu bug #1713017).

So you'll need to download the sources, install dependencies plus libasound2-dev, build and install resulting debs. You may need to add --enable-midi to debian/rules. Like this:
