# - try to find JSONCPP library
#
# Cache Variables: (probably not for direct use in your scripts)
# JSONCPP_INCLUDE_DIR
# JSONCPP_LIBRARY
#
# Non-cache variables you might use in your CMakeLists.txt:
# JSONCPP_FOUND
# JSONCPP_INCLUDE_DIRS
# JSONCPP_LIBRARIES
#
# Requires these CMake modules:
# FindPackageHandleStandardArgs (known included with CMake >=2.6.2)
#
# Author:
