It seems like OpenSSL is not installed on this system. But perhaps
|
|
you need to supply the exact location of the headers and libraries.
|
|
You can try running configure with the --with-openssl=/DIRECTORY
|
|
parameter. If you installed the headers and libraries in a different
|
|
location you can use --with-openssl-include=/DIR and
|
|
--with-openssl-lib=/DIR.
