CMakeLists.txt

# Example Daisy Web Audio Worklet CMakeLists.txt

# To get started on a new worklet, copy this entire folder (containing this file and C++ sources) to
# a convenient location, and then start making modifications.

# The first line of any CMake project should be a call to `cmake_minimum_required`, which checks
# that the installed CMake will be able to understand the following CMakeLists, and ensures that
# CMake's behaviour is compatible with the named version. This is a standard CMake command, so more
# information can be found in the CMake docs.

cmake_minimum_required(VERSION 3.15)

# The top-level CMakeLists.txt file for a project must contain a literal, direct call to the
# `project()` command. `project()` sets up some helpful variables that describe source/binary
# directories, and the current project version. This is a standard CMake command.

# `target_sources` adds source files to a target. We pass the target that needs the sources as the
# first argument, then a visibility parameter for the sources which should normally be PRIVATE.
# Finally, we supply a list of source files that will be built into the target. This is a standard
# CMake command.
