# Extra arguments are treated as source files which depend on the generated

# - Parallel builds all depend on the same files, and CMake will generate the same file multiple times in the same location.
# This can be problematic if the files are generated at the same time and overwrite each other.
# - To fix this, we create a custom target (outputTarget) that the parallel builds depend on.
# AND build dependencies. This creates the needed rebuild for appropriate source object changes.
