Openssl failing during the installation of QT 5.6.0 on Linux Suse 15.2

Hello;

We have upgraded our PCs from Linux Suse 12 to Linux Suse 15.2.

We have been asked to remain on QT 5.6.0 which was running fine on Linux Suse 12.

We want to install QT 5.6.0 on Linux Suse 15.2.

I'm getting this openssl errror when starting the installer:

Our Linux Suse 15.2 has "OpenSSL 1.1.1d  10 Sep 2019" installed

Our Linux Suse 12 had "OpenSSL 1.0.2j-fips  26 Sep 2016" installed

IT has put the folder /home/sles-12sp2/lib/ on our new machines, it contains the old openssl libs:

libnsl-2.22.so  libnsl.so.1  libssl.so.1.0.0

Doing "export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/sles-12sp2/lib" and running the same above qt-enterprise-linux-x64-5.6.0.run did Not help.

Any thoughts?

Thank you in adance for the help.
