CMake fails to add the library path for lz4 to the linker script. This causes an issue during linking where -llz4 fails.

Adding the path to `liblz4.so` to link.txt fixes the issue for me.

sed -i .bak -e 's|-llz4|-L${LOCALBASE}/lib -llz4|'} \

                ${WRKSRC}/storage/mroonga/CMakeFiles/mroonga.dir/link.txt

`LOCALBASE` in FreeBSD is set to /usr/local and liblz4 is installed there.

/usr/local/lib/liblz4.so

/usr/local/lib/liblz4.so.1

/usr/local/lib/liblz4.so.1.7.1 

/usr/local/libdata/pkgconfig/liblz4.pc

Detection of lz4 is apparently OK otherwise the code in CMakeLists would return an error.
