Alternatively, you can setup a docker container of centos7 and build
it in there on your Ubuntu machine. In combination with systems like
"mock", that is a much preferred way to cross-compile across Linux
distros. For example:

$ docker run -ti centos:centos7
Unable to find image 'centos:centos7' locally
centos7: Pulling from library/centos
Digest: sha256:4a701376d03f6b39b8c2a8f4a8e499441b0d567f9ab9d58e4991de4472fb813c
Status: Downloaded newer image for centos:centos7
[root(a)6c4ab3740af9 /]# cat /etc/redhat-release
CentOS Linux release 7.7.1908 (Core)
[root(a)6c4ab3740af9 /]#

And then:
[root(a)6c4ab3740af9 /]# yum install -y libssh-devel
...
[root(a)6c4ab3740af9 /]# ls /lib64/libcrypto*
/lib64/libcrypto.so.1.0.2k  /lib64/libcrypto.so.10
[root(a)6c4ab3740af9 /]#
