Please confirm you’re running the new script. It should include the part below. 
The “-F…” indicates that frameworks should be used. The warning you’re seeing 
was resolved when I switched to frameworks and included QT_CPPFLAGS in CPPFLAGS 
and QT_LDFLAGS in LDFLAGS.

brew switch qt5 5.12.0
QCOLLECTIONGENERATOR=qhelpgenerator
export QCOLLECTIONGENERATOR
QT_CPPFLAGS="-I/usr/local/opt/qt/include"
export QT_CPPFLAGS
QT_LDFLAGS="-F/usr/local/opt/qt/lib"
export QT_LDFLAGS

The easiest way to confirm is to edit config.log and search on "Qt LDFLAGS” 
(case-sensitive), and examine the Qt related lines. Mine are below.

  Qt CPPFLAGS:                   
-I/usr/local/Cellar/qt/5.12.0/lib/QtNetwork.framework/Headers 
-I/usr/local/Cellar/qt/5.12.0/lib/QtPrintSupport.framework/Headers 
-I/usr/local/Cellar/qt/5.12.0/lib/QtHelp.framework/Headers 
-I/usr/local/Cellar/qt/5.12.0/lib/QtWidgets.framework/Headers 
-I/usr/local/Cellar/qt/5.12.0/lib/QtGui.framework/Headers 
-I/usr/local/Cellar/qt/5.12.0/lib/QtSql.framework/Headers 
-I/usr/local/Cellar/qt/5.12.0/lib/QtXml.framework/Headers 
-I/usr/local/Cellar/qt/5.12.0/lib/QtCore.framework/Headers
  Qt LDFLAGS:                    -F/usr/local/Cellar/qt/5.12.0/lib 
  Qt GUI libraries:              -framework QtNetwork -framework QtPrintSupport 
-framework QtHelp -framework QtWidgets -framework QtGui -framework QtSql 
-framework QtXml -framework QtCore  -lqscintilla2_qt5
  Qt OpenGL libraries:           -framework QtOpenGL -framework QtWidgets 
-framework QtGui -framework QtCore 
  Qt moc:                        moc 
  Qt uic:                        uic 
  Qt rcc:                        rcc 
  Qt lrelease:                   lrelease 
  Qt qcollectiongenerator:       qhelpgenerator 
  Qt qhelpgenerator:             qhelpgenerator
