RapidJSON has become a hard dependency for OpenRAVE. Please note OpenRAVE requires the latest master branch of RapidJSON, therefore installing the
rapidjson-dev package via apt will probably not work.
This is a header-only library, but you'll probably want to disable examples and tests in order to avoid compiling stuff:
mkdir -p repos && cd repos git clone https://github.com/Tencent/rapidjson.git cd rapidjson mkdir build && cd build cmake .. -DRAPIDJSON_BUILD_DOC=OFF -DRAPIDJSON_BUILD_EXAMPLES=OFF -DRAPIDJSON_BUILD_TESTS=OFF make && sudo make install
