Example: Build Apache Arrow and PyArrow using Xrepo

[cyfdecyf]

I created a project that shows how to build Apache Arrow and PyArrow using Xrepo.

xrepo-apache-arrow

Apache Arrow has lots' of thirdparty dependencies when you enable many features. By using Xrepo, it's very easy to build Arrow and PyArrow yourself.

The project may also serve as an advanced use of Xrepo as it uses Lua script to pin package versions and configs.

@waruqi Please suggest for improvement. The add_requireconfs usage is a little complicated now.

Happy hacking with Xrepo!

try

includes("common.lua")

add_requires("arrow", arrow_configs())
add_requireconfs("**.gflags", gflags_configs({override = true}))
add_requireconfs("**.zlib", zlib_configs({override = true}))
add_requireconfs("**.bzip2", bzip2_configs({override = true}))
add_requireconfs("**.boost", boost_configs({override = true}))
add_requireconfs("**.rapidjson", rapidjson_configs({override = true}))
add_requireconfs("**.re2", re2_configs({override = true}))
add_requireconfs("**.utf8proc", utf8proc_configs({override = true}))
add_requireconfs("**.brotli", brotli_configs({override = true}))
add_requireconfs("**.lz4", lz4_configs({override = true}))
add_requireconfs("**.zstd", zstd_configs({override = true}))
add_requireconfs("**.thrift", thrift_configs({override = true}))
add_requireconfs("**.openssl", openssl_configs({override = true}))
add_requireconfs("**.libevent", libevent_configs({override = true}))
add_requireconfs("**.openssl", openssl_configs({override = true}))

or

includes("common.lua")

add_requires("arrow", arrow_configs())
for _, name for ipairs({"gflags", "zlib", "bz2", ....}) do
    add_requireconfs("**." .. name, get_xxx_configs(name, {override = true}))
end

or

add_requires("arrow.**." .. name, get_xxx_configs())

Thanks for your suggestion.

I made the change using the second variant in cyfdecyf/xrepo-apache-arrow@091c3b0 , much cleaner now. Please let me know if we can have have more improvements.
