Subject: [PATCH] fix jsoncpp detection
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The default installation path for the header files is {prefix}/json, but some
system prefers to install the headers in {prefix}/jsoncpp/json.

This patch from upstream handles both cases now when checking for the jsoncpp
library.

The patch is squashed of two commits from upstream:
1/ aba96db0cfe8a2e5c825f4448c0ad184e21b50e1
2/ ce144f19a8c2e8c1e0ec3fe53699e874e5eb43fe
