+	download and unzip the lib, cd to directory
+	mkdir build
+	cd build
+	cmake ..
+	sudo make -j4 install
+
+2) Build cppzmq via cmake. This does an out source build and installs the build files
+	download and unzip the lib, cd to directory
+	mkdir build

+Using this:
+
+A cmake find package scripts is provided for you to easily include this library.
+Add these lines in your CMakeLists.txt to include the headers and library files of
+cpp zmq (which will also include libzmq for you).
+
+#find cppzmq wrapper, installed by make of cppzmq
+find_package(cppzmq)
+if(cppzmq_FOUND)
+    include_directories(${cppzmq_INCLUDE_DIR})
+    target_link_libraries(*Your Project Name* ${cppzmq_LIBRARY})
