c bindings missing symbols?

so I built with cargo xtask build

I appear to have some stuff built

but checking with nm none of those libraries seem to contain libsql_open_ext

I made a little script for checking for everything cmake complains about

Symbol check complete.

Reproduce the failure with cargo xtask build and cmake --build ., then inspect the generated libraries under libs/libsql/libsql-sqlite3/.libs/ and the CMake target linking langchain_test. Verify where the listed libsql_* symbols should be produced and exported; done means the symbols are present and the executable links successfully.
