I know nothing about glslang, but:

This is the commit that introduced these new libraries on June 30 2020:
https://github.com/KhronosGroup/glslang/commit/b8c3386ec00b9de2925732c0a29c588d60f8c8fd

I'm also sure your change will break build against glslang older than
that commit.

glslang didn't put any (internal or external) version bump into this
commit, and hasn't released it. There does exist a GLSLANG_PATCH_LEVEL,
perhaps you can test against that, or just test whether the configure
tests fails with those new libs, and fall back to using only the old
list.

Just speculation,
