# Adam is currently doing a hybrid of the CMAKE tutorial, and MBolus's template
# https://cmake.org/cmake/help/latest/guide/tutorial/index.html
# example code here: https://github.com/mbbill/CMake-Tutorial
# https://github.com/maks-it/CMake-Tutorial
#
# [x] Step 1 - something builds as long as it doesn't depend on something else
# [x] Step 2 - adding library, conditional includes
# [?] Step 3 - "usage requirements"
# [x] Step 4 - install & testing
