libmysofa: add package

[luadebug]

wasm:

In file included from /home/runner/.xmake/cache/packages/2412/l/libmysofa/v1.3.2/source/src/hrtf/reader.c:18:
/home/runner/.xmake/cache/packages/2412/l/libmysofa/v1.3.2/source/src/hrtf/portable_endian.h:117:3: error: platform not supported
  117 | #       error platform not supported
      |         ^

Yet it seems emscripten is kind of behaving like different os, it defines unix, unix, EMSCRIPTEN all time, so currently there is either overwrite logic of portable endian h(to support it since it looks like it wont work over emscripten at all) or either doing something like if is_host("linux") then replace(defined(linux), 1)... Or just limit wasm.
feel free to change & merge.
BTW, I dont know if there is need to rename package name from libmysofa to mysofa... I think it is fine it won't affect over find_package(MySOFA) at all.

proj points to mysofa-shared.vcxproj everytime.... too troublesome to fixup these flags... My attempt to exclude BUILD_STATIC_LIBS did not go as expected... 😕😕😕

I don't know you mean, you can try

table.insert(configs, "-DBUILD_STATIC_LIBS=" .. (package:config("shared") and "OFF" or "ON"))
table.insert(configs, "-DBUILD_SHARED_LIBS=" .. (package:config("shared") and "ON" or "OFF"))

Is it set_license("BSD-3-Clause")?

Yes, We can reference https://archlinux.org/packages/extra/x86_64/libmysofa

Try to patch cmake to use xrepo zlib for unbundle deps.

We can apply this patch to improve shared library build.

IDK maybe we should limit Wasm here, because

xmake-repo/packages/l/libkmod/xmake.lua

Lines 14 to 19 in aa72d47

	on_install("linux", "android", function (package)
	os.cp(path.join(package:scriptdir(), "port", "xmake.lua"), "xmake.lua")
	os.cp(path.join(package:scriptdir(), "port", "config.h"), "config.h")
	os.cp(path.join(package:scriptdir(), "port", "endian-darwin.h"), "endian-darwin.h")
	import("package.tools.xmake").install(package)
	end)

is limited to Linux, android & rely over endian-darwin.h just as shown in Wasm error log of this port with Unsupported platform error.

https://github.com/xmake-io/xmake-repo/blob/aa72d472b106727cf9cd823f1ce675e0c4c19ff5/packages/l/libkmod/port/endian-darwin.h is same as https://github.com/hoene/libmysofa/blob/main/src/hrtf/portable_endian.h
Well left to do is limit Wasm & done or either going something https://gitlab.b-data.ch/qgis/qgis/-/blob/final-3_24_2/external/laz-perf/portable_endian.hpp?ref_type=tags#L13-15 which points to https://github.com/hobuinc/laz-perf/blob/2b68700d33bf981d257d6101d96714620c64019c/cpp/lazperf/portable_endian.hpp#L15
It is not chosen by upstream and I'm not sure to go this way or not.

[luadebug]

Should it be there || defined(__EMSCRIPTEN__) or its better limit wasm build ? https://github.com/hobuinc/laz-perf/blob/2b68700d33bf981d257d6101d96714620c64019c/cpp/lazperf/portable_endian.hpp#L15
maybe || defined(__GNU__) as well. Though it looks very preferable to just replace existing file with this one.
Well it seems it helped WASM CI for some reason.

If the library documentation says that the platforms (wasm/ios etc...) is supported, but it failed in xrepo ci, we can limit it in on_check.

xmake-repo/packages/i/igraph/xmake.lua

Lines 25 to 31 in 95aa0e9

	on_check(function (package)
	if package:is_cross() then
	if not package:is_plat("windows", "macosx") then
	raise("package(igraph) unsupported cross-compilation now. To support it, see https://igraph.org/c/html/latest/igraph-Installation.html#igraph-Installation-cross-compiling")
	end
	end
	end)

I don't find anything that states out, libmysofa supports wasm/emscripten or not (https://github.com/ColumbiaCEAL/libmysofa-wasm/blob/main/README.md portable endian h not found there). I believe it should pass CI after changing portable endian header, as it is shown in other repo.
Prolly need patch portable endian to support emscripten or borrow it from lazpack repo. Yet I hope I patch it to support wasm properly, hence it repeat lazperf s emscripten support, i believe... %_% At least it helped CI.
