libprocess-cpp-dev binary package in Ubuntu Oracular riscv64

 process-cpp is a simple and straightforward wrapper around process creation
 and control. It helps both with handling child processes and with interacting
 with the current process. Some of its features include:
 .
  - Thread-safe get/set/unset operation on the current process's environment.
  - Throwing and non-throwing overloads of functions when system calls are
    involved.
  - Seamless redirection of input, output and error streams of child processes.
  - Type-safe interaction with the virtual proc filesystem, both for reading &
    writing.
 .
 This package includes all the development headers and libraries for
 process-cpp.
