As it turns out, no, I can't use Qt5.  In fact, I'd love to hear from  
anyone who actually has.  I find this in Modules/FindQt.make:

===========================
if (Qt_FIND_VERSION)
   if (Qt_FIND_VERSION MATCHES "^([34])(\\.[0-9]+.*)?$")
     set(DESIRED_QT_VERSION ${CMAKE_MATCH_1})
   else ()
     message(FATAL_ERROR "FindQt was called with invalid version  
'${Qt_FIND_VERSION}'. Only Qt major versions 3 or 4 are supported. If  
you do not need to support both Qt3 and Qt4 in your source consider  
calling find_package(Qt3) or find_package(Qt4) instead of  
find_package(Qt) instead.")
   endif ()
endif ()
===========================

So I re-installed Qt4, rebuilt CMake (./bootstrap --qt-gui, make, sudo  
make install) and still got the same runtime failure.
