do you have the libapr-devel or libapr1-devel package installed?  On
debian and debian-derived systems, the package that contains these
development header filess is called libapr1-dev, and it places them in
/usr/include/apr-1.0/ -- i don't have enough experience with RHEL 7.3 to
know exactly where they would be placed on that version of that
distribution.

hth,
