In order Geonkick to run and operate correctly there is a need

for standalone:

• GNU/Linux operating system
• Jack server running

for plugin:

• GNU/Linux or Windows operating system.
• A host that supports LV2 or VST3 plugin format.

In order to build Geonkick there is a need to install the following development packages:

• libsndfile
• OpenSSL
• RapidJSON
• JACK Audio Connection Kit
• LV2 development library

On Debian, Ubuntu, Ubuntu Studio install:

apt-get install build-essential cmake libjack-dev libsndfile-dev rapidjson-dev lv2-dev libcairo2-dev

Clone the Geonkick code repository, compile and install.

    copy the source code of the latest release
    mkdir geonkick/build
    cd geonkick/build
    cmake ../
    make
    make install

Get VST3 SDK than build Geonkick VST3 plugin:

    mkdir geonkick/build
    cd geonkick/build
    cmake -DVST3_SDK_PATH=<full system path to VST3 SDK folder> -DSMTG_ENABLE_VST3_PLUGIN_EXAMPLES=OFF -DSMTG_ENABLE_VST3_HOSTING_EXAMPLES=OFF -DSMTG_ENABLE_VSTGUI_SUPPORT=OFF ../
    make
    make install

To build on Windows, there is a need to install MSYS2/UCRT64 and follow the same steps as mentioned above. Alternatively, you can refer to the 'Building' step in the file .github/workflows/windows.yml of Geonkick repository.
