# Get the directory containing the file currently being processed.

# This is equivalent to getting the value of CMAKE_CURRENT_LIST_DIR in
# cmake versions greater than 2.8.4, but we provide this wrapper macro
# for compatibility. If called outside of a function or macro, this
# will return the directory of the calling file. If called within a
# function or macro, this will return the directory containing the
# caller.
