configure: error: Package requirements (libcrypto >= 1.0.1) were not met:

Package 'libcrypto', required by 'virtual:world', not found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables crypto_CFLAGS
and crypto_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
