Error during configure (ERROR: No openssl crypto library found!)

[badbeef]

Describe the bug Seeing the following error during ./configure on Ubuntu 18

configure: ERROR: No openssl crypto library found!

I already have openssl, autoconf, automake and libtool installed.

To Reproduce ./configure --with-crypto=openssl

Seeing: configure: ERROR: No openssl crypto library found!

Specify --with-crypto=$backend and/or the neccessary library search prefix.

Known crypto backends: auto, openssl, libgcrypt, mbedtls, wincng configure: error: Required dependencies are missing!

Expected behavior Expect ./configure to succeed

Version (please complete the following information):

• OS and version: Ubuntu 18
• libssh2 version: 1.10.0 (latest)
• crypto backend: OpenSSL installed with apt install openssl

Additional context Add any other context about the problem here. I am new with libssh2. Just want to compile and try out its examples. I am not sure what part of openssl libssh2 is looking for. I see my distribution has /usr/lib/x86_64-linux-gnu/libssl.so.1.1 . I tried adding --with-libssl-prefix=/usr/lib/x86_64-linux-gnu and that didn't work either.

You need to install the development libraries for openssl if you're compiling against it, namely libssl-dev. "openssl" just contains some config files and man pages.

closing as a configuration issue, but a bug.
