#  Point BSON_INCLUDES and BSON_SHLIB where the BSON development resources live
#  as installed separately before making this extension:
#  Examples:
#    OS X:  brew install mongo-c-driver
#      -I/opt/homebrew/Cellar/mongo-c-driver/1.23.2/include/libbson-1.0/bson
#      -L/opt/homebrew/Cellar/mongo-c-driver/1.23.2/lib -lbson-1.0
#
#    RH:    sudo dnf install epel-release
#           sudo yum install libbson-devel.x86_64
#           -I/usr/include/libbson-1.0/bson
#           -L/usr/lib64 -lbson-1.0
#  
#  It is very important that the lib can be found at the proper path
#  AT RUNTIME by postgres; that is the purpose of the -L option.  This
#  should probably be something like /usr/local/lib,
#  /usr/local/lib/postgres, /usr/lib64, etc.
#  Wherever pgbson.so (or pgbson.dylib) gets installed, check with ldd (or
#  otool -L) that it knows about libbson e.g.:
#        $ ldd /usr/pgsql-16/lib/pgbson.so
#            linux-vdso.so.1 (0x00007ffc78f22000)
# good! -->  libbson-1.0.so.0 => /lib64/libbson-1.0.so.0 (0x00007fc6cfb20000)
#            libc.so.6 => /lib64/libc.so.6 (0x00007fc6cf800000)
#            /lib64/ld-linux-x86-64.so.2 (0x00007fc6cfb71000)
#
#        $ ls /lib64/libbson-1.0.so.0
#        /lib64/libbson-1.0.so.0  # found!  good!
#
#  This is the only external dependency of this extension.
