I first have built OpenSSL (1.1.0.c, which built fine), then tried to build
libssh2. Libssh2 (1.8.0) is configured with:
CDPATH= cd /vobs/obj.RHAT7/thirdparty/libssh2/64bit/libssh2-1.8.0; CC=gcc
CFLAGS=" -m64 -march=corei7 -mmmx -msse -msse2 -msse3 -msse4 -mfpmath=sse "
MAKEFLAGS= MFLAGS= ./configure
--prefix=/vobs/obj.RHAT7/thirdparty/libssh2/64bit/libssh2-1.8.0/build
--without-libz --with-openssl
--with-libssl-prefix=/vobs/obj.RHAT7/thirdparty/OpenSSL/64bit/openssl-1.1.0c/build

Note the 'lib64' part in
/vobs/obj.RHAT7/thirdparty/OpenSSL/64bit/openssl-1.1.0c/build/lib64/libssl.a.
This is unexpected for me, and probably incorrect in the configure script
(additional_libdir="$withval/$acl_libdirstem" from configure:16521. I don't
know why the configure script likes to take 'lib64', while there is no
necessary relationship by a user provided prefix dir for OpenSSL and a system
lib64 prefix (acl_libdirstem is set at line 14237, and is related to something
else than OpenSSL, isn't it)?
Why is $acl_libdirstem used for OpenSSL (and also for some others, e.g.
libbcrypt_prefix)?
Even replacing additional_libdir="$withval/$acl_libdirstem" by
additional_libdir="$withval/lib" did not fully help. Now the libs are correctly
set, but the include (-I flag) is still omitted, see configure output:

configure:16965: $? = 1
There are at least two issues: wrong LIB path and missng include path.
The missing include path is probably related to the reset of
additional_includedir= directive in configure:16737 (and also using
$acl_libdirstem). I'm not sure.
For me libssh2 is not very important on Linux/UNIX (I only use it for now on
Windows). If I have time, I will perform more checking to figure out why the
include path is not correctly added to the compiler flags.
Maybe you are already able to draw a conclusion on previous output.

I think the configure log might help *you* figure out why the script fails to
detect openssl.
Did something change in terms of placement of libraries when openssl was
bumped to 1.1.0 ? I've build libssh2 with openssl 64 bit since basically
forever.
