CMakeLists.txt

# To get started on a new plugin, 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.
