tildearrow 061991fe60 desubmodulize libsndfile - PLEASE READ
it appears a one-character typo in the cmake_minimum_required line prevents it from compiling under CMake 4.0.
in order to fix that, I had to take this thing out of submodules...

it is recommended to do this after you pull;

git submodule deinit extern/libsndfile
