Some more details:

If I query cmake for variables referring to Qt libraries, it all refers 
to the correct libraries for my build:

%> cmake -LA | grep Qt | grep ".so"

Unfortunately the final libmarblewidget build result is still linked 
against the incorrect system Qt:

%> ldd  /opt/marble/lib/libmarblewidget.so | grep Qt
         libQtCore.so.4 => /usr/lib/x86_64-linux-gnu/libQtCore.so.4
         libQtGui.so.4 => /usr/lib/x86_64-linux-gnu/libQtGui.so.4
         libQtXml.so.4 => /usr/lib/x86_64-linux-gnu/libQtXml.so.4
         libQtSvg.so.4 => /usr/lib/x86_64-linux-gnu/libQtSvg.so.4
         libQtNetwork.so.4 => /usr/lib/x86_64-linux-gnu/libQtNetwork.so.4
         libQtWebKit.so.4 => /usr/lib/x86_64-linux-gnu/libQtWebKit.so.4
 
libQtDeclarative.so.4=>/usr/lib/x86_64-linux-gnu/libQtDeclarative.so.4
         libQtScript.so.4 => /usr/lib/x86_64-linux-gnu/libQtScript.so.4
         libQtSql.so.4 => /usr/lib/x86_64-linux-gnu/libQtSql.so.4
         libQtXmlPatterns.so.4 => 
/usr/lib/x86_64-linux-gnu/libQtXmlPatterns.so.4



Still digging....
