error: ‘rapidjson’ has not been declared

When building from commit 92cdaca62f3ce2e0a81140df28279b24c84d5e52 I get:

not sure we can remove rapidjson dependency from the current (heavily depend) state. simply make install Tencent/rapidjson, or stick with 951676167e443eec6b40163d4f5b68d0858b74ef for now

I have had already installed rapidjson before, using sudo apt-get install rapidjson-dev to fix libopenrave-core/libopenrave0.10-core.so.0.10.0: undefined reference to OpenRAVE::InterfaceBase::SupportsJSONCommand(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)' collect2: error: ld returned 1 exit status

Installing rapidjson from source on top of the installation via apt-get fixed the issue.

perhaps you would need to remove cmake cache and reconfigure

Looks like rapidjson is a hard (required) dependency on latest master. The following block as well as all occurrences of OPENRAVE_RAPIDJSON could be removed, I guess:

Just in case somebody missed it due to how my comment was worded (i've updated it now): installing rapidjson from source on top of apt-get installation fixed the issue for me.

Installing rapidjson-dev on ubuntu 18.04 fixed this error me, no need to install from source. But I completely removed the cmake cache.
