description         International Components for Unicode

long_description \
    The International Components for Unicode (ICU) libraries provide robust \
    and full-featured Unicode services on a wide variety of platforms. ICU \
    supports the most current version of the Unicode standard, and they provide \
    support for supplementary Unicode characters (needed for GB 18030 repertoire support).

# Note 1:
    # prior to 10.14, universal means different library bit depths or endianness,
    # so we had to build separately and lipo together using the muniversal PG

    # We can't easily use the muniversal PG on darwin20+ (footnote 2), however we don't
    # need to use it because the universal build there has the same library bit
    # depth and endianness on both Intel and arm64. Therefore we can build universal in
    # one pass using clang's ability to generate both archs at once.


# Note 2:
    # ICU needs to run binaries when building, to generate its data.
    # Simply disallowing cross compiling is the simplest solution, however
    # that means that an x86_64/arm64 universal version can never be built on an Intel Mac.
    # ancient refs: #29904, ancient solutions tried (r79660, r73865, and r73849)

# Note 3:
    # Remove architecture-specific differences to allow merging. (See note 2).
    # we do not believe icu-config uses SIZEOF_VOID_P. Projects using Makefile
    # include files may experience problems. The developers of ICU suggest using
    # pkg-config over both icu-config and the Makefile includes.
    # calling icu-config for the host information is not mentioned in any
    # icu man pages, differs between architectures, and can't be merged

    # ICU has three mechanisms to aid other projects in building properly
    #     1) .pc files for pkg-config
    #     2) shell script icu-config that can output compiler flags
    #     3) Makefile include files Makefile.inc and pkgdata.inc
    # For a time, all three assumed other projects would want to be
    #     built as ICU had been built, regardless of whether it was appropriate.
    # For the most part, the extraneous flags have been removed.
    #     1) They have been removed completely from the .pc files.
    #        pkg-config is the recommended way of building against ICU.
    #     2) icu-config does not print them out, but they are still contained in the script itself.
    #     3) They still exist in the Makefile include files.
