building mariadb 10.0.15 on linux/64

i have a non-system instance of (lib)pcre, installed in /usr/local/test/pcre, that i need to build/link against

reading

 Link MariaDB Client Library for C with specific external zlib and openssl
  https://mariadb.com/kb/en/mariadb/client-libraries/client-library-for-c/link-mariadb-client-library-for-c-with-specific-external-zlib-and-openssl/ 

i've built with

	cmake ..  \
	 ...
	 -DCMAKE_C_FLAGS="... -I/usr/local/test/pcre/includes" \
	 -DCMAKE_CXX_FLAGS="... -I/usr/local/test/pcre/includes" \
	 -DCMAKE_SHARED_LINKER_FLAGS="... -L/usr/local/test/pcre/lib64 -lpcre" \
	 ...

and

	cmake ..  \
	 ...
	 -DCMAKE_C_FLAGS="... -I/usr/local/test/pcre/includes" \
	 -DCMAKE_CXX_FLAGS="... -I/usr/local/test/pcre/includes" \
	 -DCMAKE_SHARED_LINKER_FLAGS="... -L/usr/local/test/pcre/lib64 -Wl,-rpath,/usr/local/test/pcre/lib64 -lpcre
" \
	 ...

but id both cases, the resultant binary still links against system pcre libs

	ldd sql/mysqld | egrep -i "pcre"
		libpcre.so.1 => /usr/lib64/libpcre.so.1 (0x00007f6165a5e000)

what's the correct method for linking against a specified, non-system path'd lib?  specifically, here, libpcre?
