    setup: Missing dependency on a foreign library:
    * Missing (or bad) header file: openssl/evp.h
    This problem can usually be solved by installing the system package that
    provides this library (you may need the "-dev" version). If the library is
    already installed but in a non-standard location then you can use the flags
    --extra-include-dirs= and --extra-lib-dirs= to specify where it is.
    If the header file does exist, it may contain errors that are caught by the C
    compiler at the preprocessing stage. In this case you can re-run configure
    with the verbosity flag -v3 to see the error messages.
