Don't do that. That is almost certainly the cause of these errors. The 
".h.in" files are *not* header files ready for use. They are templates 
from which we generate the real header files.

You need to build OpenSSL first before you can use the headers. Refer to 
the INSTALL.md file for instructions. Alternatively you can just 
download a pre built version from a third party distributor. See:
