Introduced PCRE2_CFLAGS, PCRE2_LDADD, and PCRE2_LDFLAGS in all relevant Makefile.am files to align with the existing PCRE_* variable usage. This change addresses potential issues with linking and configuration for builds on macOS GitHub runners.
These modifications aim to resolve the build failure observed exclusively in the macOS environment while maintaining compatibility across other platforms. Testing will confirm if this adjustment corrects the issue.
