I m building ceph cmake command 

>cd build/

>cmake -DWITH_SEASTAR=ON ..

but it is giving error with following message "could not find crptopp_LIBRARY and crytopp_INCLUDE"

crytopp is defined in "SeastarDependencies.cmake" with other dependencies like protobuf(this is also not building), yaml-cpp etc

I built this branch on latest ceph repo, any kind of hint will be helpful.

Thanks. Regards
