compiling Apache httpd 2.4 with mod_nss - configure.sh ignoring --with-nss= option (Apache Users)

Apache 2.4.29 on RHEL 7.4

I need to compile Apache with --prefix so that I can manage it with a non-privileged account, thus I am avoiding the RHEL provided RPMs. I am trying to compile Apache 2.4.29 from scratch with mod_nss included.

I am configuring using:

./configure --with-apxs --prefix=/opt/apps/httpd-2.4.29 --enable-mods-shared="all cgi nss" --enable-mpms-shared='all' --with-nss=/opt/local/ --with-nspr=/opt/local/ --enable-mods-shared

However, I do not see that any action is taken on the --with-nspr or --with-nss options. I was hoping that Apache would complain about not being able to find suitable files to build such if there is a problem, but it doesn't, instead appearing to just ignore them. I have tried both with the Mozilla provided packages (compile fine on my box) and also with RHEL provided nspr & nss as shown below:

$ rpm -qa | grep nss | grep -v open nss-softokn-freebl-devel-3.28.3-8.el7_4.x86_64 libsss_nss_idmap-1.15.2-50.el7_4.8.x86_64 nss-3.28.4-15.el7_4.x86_64 nss-util-devel-3.28.4-3.el7.x86_64 nss-softokn-devel-3.28.3-8.el7_4.x86_64 nss-sysinit-3.28.4-15.el7_4.x86_64 nss-softokn-freebl-3.28.3-8.el7_4.x86_64 nss-devel-3.28.4-15.el7_4.x86_64 nss-util-3.28.4-3.el7.x86_64 jansson-2.10-1.el7.x86_64 nss-tools-3.28.4-15.el7_4.x86_64 nss-softokn-freebl-3.28.3-8.el7_4.i686 nss-pem-1.0.3-4.el7.x86_64 nss-softokn-3.28.3-8.el7_4.x86_64

$ rpm -qa | grep nspr nspr-devel-4.13.1-1.0.el7_3.x86_64 nspr-4.13.1-1.0.el7_3.x86_64

Apache is not attempting to find either package, or atleast doesn't complain about not finding them. Any help is appreciated.
