Can't find $libdir/duckdb_fdw about duckdb_fdw

[nestarz]

After make install, the extension files are not placed into the right directory, nothing seems to happen in fact, I need to manually copy them, but still where is the duckdb_fdw I need to copy to $libdir ?

Made it work by only copying the required files:

FROM postgres

RUN apt-get update && apt-get install -y \
  git \
  build-essential \
  cmake

RUN git clone https://github.com/cwida/duckdb.git \
  && cd duckdb \
  && make

RUN apt-get install -y postgresql-server-dev-13 postgresql-client-13

RUN git clone https://github.com/alitrack/duckdb_fdw.git  \
   && cd duckdb_fdw \
   && cp /duckdb/build/release/tools/sqlite3_api_wrapper/libsqlite3_api_wrapper.so $(pg_config --libdir)  \
   && cp /duckdb/tools/sqlite3_api_wrapper/include/sqlite3.h .  \
   && make USE_PGXS=1 \
   && make install USE_PGXS=1 \
   && cd .. && rm -rf duckdb_fdw duckdb
