# NOTES about adding Externals:
#   - If an external provides a target, or one can be introduced with find_package, consider using it.
#     - If a target doesn't exist, consider introducing a target for it with add_library and adding all necessary
#       includes, definitions, etc, to that target. This way, only libraries that need those attributes simply
#       need to link that target in, as opposed to them being provided to every library
#       (which is the case with the directory-based include_directories, add_definitions, etc)
#
#   - make sure to tell cmake to link them statically or dynamically (most
#     should be linked statically)
#   - place the CMakeLists.txt in the first-level subdirectory, e.g.
#     Externals/zlib/CMakeLists.txt (that is: NOT in some Src/ subdirectory)
