see below – I just realized that openssl-1.1.1 is present in centOS7:
 
openssl version
OpenSSL 1.1.1o  3 May 2022 (Library: OpenSSL 1.1.1k  FIPS 25 Mar 2021)
 
As suggested I edited the PKG_CONFIG_PATH -->
 
echo $PKG_CONFIG_PATH
/usr/local/ssl/
 
Now I, however, unsuccessfully tried three configure options:
 
1.) Configuring Qt without additional parameters tells me:
 
Qt Network:
OpenSSL ................................ no
Qt directly linked to OpenSSL .... no
OpenSSL 1.1 ........................... no
 
and in turn does not include openssl into the build
 
2.) ./configure -ssl
 
does the same mentioned in 1.) plus
 
ERROR: Feature 'ssl' was enabled, but the pre-condition 'config.winrt || features.securetransport || features.openssl || features.schannel' failed.
 
3.) ./configure -ssl -openssl-linked
 
does the same mentioned in 1.) plus

ERROR: Feature 'openssl-linked' was enabled, but the pre-condition '!features.securetransport && !features.schannel && libs.openssl' failed.
ERROR: Feature 'ssl' was enabled, but the pre-condition 'config.winrt || features.securetransport || features.openssl || features.schannel' failed.
 
Any more hints towards final success :-) ?
 
Thank you
 
Alex

Build OpenSSL 3 and add its install directory lib/pkgconfig to PKG_CONFIG_PATH and choose -openssl-linked as one of the config parameters.  If you can get through configure, it should build.

I'm going to guess that this means the type QSslConfiguration is unknown.

You need OpenSSL 1.1 to enable SSL support in QtNetwork 5.15.
