is naive. it ignores commonplace multiarch support.
with =path enabled on config, generated Makefile is just wrong
egrep "^LMDB" Makefile
LMDB_CFLAGS = -I/usr/local/lmdb/include
LMDB_LIBS = -L/usr/local/lmdb/lib none required
bind advertises
./configure --help | grep -i LMDB
--with-lmdb=PATH build with LMDB library [yes|no|path]
it simply fails to work as advertised.
> you can use and adjust the .pc file from any Linux distribution package
of course you can.
it's here
pkg-config --libs --cflags lmdb
-I/usr/local/lmdb/include -L/usr/local/lmdb/lib64 -llmdb
> LMDB support in BIND 9 comes with pkg-config support too
there's NO such option advertised by bind configure, as
LMDB_CFLAGS
C compiler flags for LMDB, overriding pkg-config
LMDB_LIBS
linker flags for LMDB, overriding pkg-config
it's simply not used by this bind build
grep PKG_CHECK `grep -rln PKG_CHECK .` | grep -i lmdb
(empty)
& no mention at all of it in source
grep -i lmdb `grep -rlni lmdb .` | grep -i pkg
(empty)
this
--with-openssl=/usr/local/openssl
works.
this,
--with-lmdb=/usr/local/lmdb
does not.
That has _nothing_ to do with 'LMDB upstream'

neither.

is about as simple as it gets.
fix it, remove it, or leave it as is -- your product, your choice.
good luck.
