I noticed an issue so far with CMAKE under Windows and Visual Studio 2013:PCRE2_BUILD_PCRE2_8 = ON works, but switching on PCRE2_BUILD_PCRE2_16 and PCRE2_BUILD_PCRE2_32, too, causes function prototype conflicts (same name exported/defined several times).
This only happens when BUILD_SHARED_LIBS is enabled. --## List details at https://lists.exim.org/mailman/listinfo/pcre-dev
