# Welcome to VST 3 SDK cmake

This repository contains Steinberg's [cmake modules](https://cmake.org/cmake/help/latest/manual/cmake-modules.7.html) and template files which can be used to create **VST 3** plug-ins for platforms like Windows, macOS, iOS and Linux.

For more information about cmake visit [cmake.org](https:://www.cmake.org/).

## Dependency map

In order to build a plug-in successfully, it only needs to link to ```sdk``` library. [VSTGUI](https://steinbergmedia.github.io/vst3_dev_portal/pages/What+is+the+VST+3+SDK/VSTGUI.html) is optional and can be used by linking to ```vstgui_support```.

The following figure shows the dependency map by using AGain, [EditorHost](https://steinbergmedia.github.io/vst3_dev_portal/pages/What+is+the+VST+3+SDK/EditorHost.html) and [VST3Inspector](https://steinbergmedia.github.io/vst3_dev_portal/pages/What+is+the+VST+3+SDK/VST3Inspector.html):

## Naming conventions and guidelines

Steinberg module, macro, function and variable names have the prefix ```SMTG_``` or ```smtg_``` in order to avoid name clashes.

### File namings

Steinberg module names are written in camel case and have the prefix ```SMTG_```.

Examples:

```c
SMTG_AddVST3Library.cmake
SMTG_DetectPlatform.cmake
SMTG_ConfigureCmakeGenerator.cmake
```

### Macro and function namings

Steinberg macro and function names are written in lower case and have the prefix ```smtg_``` followed by a verb.

Examples:

```c
smtg_detect_platform
smtg_configure_cmake_generator
smtg_setup_symbol_visibility
smtg_detect_xcode_version
```

### Variable namings

Steinberg variable names are written in upper case and have the prefix ```SMTG_```.

Examples:

```c
SMTG_PLUGIN_BINARY_DIR
SMTG_PLUGIN_EXTENSION
SMTG_PLUGIN_PACKAGE_NAME
```
