More likely, you have not installed the "openssl-dev",
"openssl-headers" or similarly named package which provides
the parts of an OpenSSL installation only needed when
building software.  Not installing that part of libraries
by default is standard practice, as the total sum of all
such parts for all installed libraries takes up a lot of
disk space.
