Add pcre2 include dir (required for non-system PCRE2 installations)

pkg-config provides users with the include path `../include/r3`
while CMake installs the headers directly under `../include/`.
This corrects the installation path to match the generated r3.pc
and to get the same result as when using autoconf.
