add CMake package configuration file
This will enabled other CMake-based projects to find an installed version of cpp-netlib via find_package(cppnetlib [[VERSION] 0.10.1] [REQUIRED]) To link to the installed cppnetlib version projects want to use include_directories(${CPPNETLIB_INCLUDE_DIRS}) target_link_library(myTarget ${CPPNETLIB_LIBRARIES})
