 From what I can see on the OpenSSL web site[1], 1.0.2o and 1.1.0h /are/the 
latest in those lines.  The only other one available is "1.1.1-pre8", which 
I'm assuming is not a release version.

I build from clean extractions of the source archive every time, and blow away 
the folder after the build completes (whether successful or unsuccessful).  
This is not an issue.

I don't have a "qt_lib_network.pr" file.  I have "qt_lib_network.pri" in that 
folder, and it contains the following after the build fails to link with OpenSSL:

    QT_MODULE_BIN_BASE = Q:/Qt/build/64_dll/qtbase/bin
    QT_MODULE_INCLUDE_BASE = Q:/Qt/build/64_dll/qtbase/include
    QT_MODULE_LIB_BASE = Q:/Qt/build/64_dll/qtbase/lib
    QT_MODULE_HOST_LIB_BASE = Q:/Qt/build/64_dll/qtbase/lib
    QT.network.priority = 1
    QT.network_private.priority = 1

It doesn't contain Qt.network.* anything, even though configuration tests report:

    Checking for OpenSSL... yes
    Checking for OpenSSL 1.1 support... yes
    OpenSSL ................................ yes
    Qt directly linked to OpenSSL ........ yes
    OpenSSL 1.1 ............................ yes

I'm not using OPENSSL_LIBS to "override the default library names."  Perhaps I 
should do that and see if it changes the results.
