+Subject: [PATCH] fix install without static libzmq
+
+If libzmq is only available as a shared library and not a static one
+then cmake fails with:
+
+-- CMake libzmq package not found, trying again with pkg-config (normal install of zeromq)
+-- Found PkgConfig: /home/fabrice/buildroot/output/host/bin/pkg-config (found version "0.28")
+CMake Error at CMakeLists.txt:20 (message):
+  ZeroMQ was not found, neither as a CMake package nor via pkg-config
+
+This is due to the fact that ZeroMQ_FOUND is not set to ON even if
+ZEROMQ_LIBRARY is TRUE:
+
+if(ZeroMQ_LIBRARY AND ZeroMQ_STATIC_LIBRARY)
+    set(ZeroMQ_FOUND ON)
+endif()
+
+So change AND by OR as suggested in
+https://github.com/zeromq/cppzmq/issues/266
+
+Fix #266
