CMake Error at /usr/share/cmake-3.10/Modules/CMakeFindDependencyMacro.cmake:48 (find_package):
By not providing "FindJsoncpp.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "Jsoncpp", but
CMake did not find one.

Could not find a package configuration file provided by "Jsoncpp" with any
of the following names:

JsoncppConfig.cmake
jsoncpp-config.cmake

Add the installation prefix of "Jsoncpp" to CMAKE_PREFIX_PATH or set
"Jsoncpp_DIR" to a directory containing one of the above files. If
"Jsoncpp" provides a separate development package or SDK, be sure it has
been installed.
