# Configuring and building the JASPEngine. To build JASPEngine we need the R-Interface, and
# the `add_dependencies` takes care of this dependency, however, there is a subtle difference
# between how it works on Windows compared to other OSes. On Windwos, R-Interface is a
# custom target, while on other OSes its a target defined by `add_library`.
#
# On Windows,
#   - We need to manually link to the R-Interface.dll.a and also place the R-Interface.dll
#     inside the build folder.
