Source: libssh2

--------------------
if libssl-dev is removed, or libssl1.0-dev installed then it builds OK.
So it seems that the package should declare a build-conflicts with libssl-dev.
The underlying reason appears to be an API change to opaque structs, explained
on:
https://wiki.openssl.org/index.php/OpenSSL_1.1.0_Changes
and covered in a debian context in:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=857621
I've not worked out the full details of why this works so long as the
headers are not present at all, but the issue is that
/usr/include/openssl/dsa.h (or rsa.h) defines a struct DSA_SIG_st but
not the contents of it, which is now an internal detail not exposed in
the headers.
presumably by the magic of autoconf, if no openssl headers are found
then nothing tries to be too cleaver and access struct members
directly.
I tried this on two architectures and both fail the same way.
