# When adding nanoarrow's CMake directory to a CMake project that contains a library
# intended for use by others, set NANOARROW_NAMESPACE to rename symbols in the
# nanoarrow library such that they do not collide with other libraries that may also
# link to their own copy of nanoarrow. You may wish to include the namespace only
# on release builds, since the namespace implementation obscures inline help
# available in many text editors.
