Is your feature request related to a problem? Please describe.

https://github.com/GNOME/libxml2/blob/dd4c0f62fa1fd9650aae6b718dd9964a4ffa69b9/CMakeLists.txt#L35C8-L35C26

option(LIBXML2_WITH_LZMA "Use liblzma" OFF)

vcpkg/ports/libxml2/vcpkg.json

Lines 18 to 22 in d172727

	"default-features": [
	"iconv",
	"lzma",
	"zlib"
	],

This difference causes link failure when building lxml from source as it does not link liblzma.

Proposed solution

Turn the lzma feature off by default

Describe alternatives you've considered

One can reinstall libxml2 with lzma disabled, but such discrepancy with the upstream will keep causing confusion.
