build: Cmake not finding SQLite3 when python/sqlite is in "non-standard" path

I use a python version that is part of Intel's oneAPI toolkit, which includes sqlite3

$ which sqlite3
/opt/intel/oneapi/intelpython/latest/bin/sqlite3
$ sqlite3 --version
3.38.0 2022-02-22 18:58:40 40fa792d359f84c3b9e9d6623743e1a59826274e221df1bde8f47086968a1bab

The sqlit3.h file is in /opt/intel/oneapi/intelpython/latest/include and libsqlite3 is in /opt/intel/oneapi/intelpython/latest/lib.

When configuring ns-3, ns3/CMake finds python in the non-standard path (/opt/intel/oneapi/intelpython/latest) as you can see below. However, it does not find sqlite3

$ CXX="clang++" ./ns3 configure --build-profile=debug --enable-tests --enable-examples --disable-python

Am I missing/overlooking something?
