[oe] [meta-oe] erros building poppler_0.26.5.bb with --enable-poppler-qt4

[Marco Cavallini]

I used to build poppler + qt4 with dora and now I need the same with dizzy.
Unfortunately I am facing to some errors.

I edited poppler_0.26.5.bb enabling --enable-poppler-qt4
then I changed configure.ac patching the library names and adding 'E'.

AC_ARG_ENABLE(poppler-qt4,
              AC_HELP_STRING([--disable-poppler-qt4],
                             [Don't compile poppler Qt4 wrapper.]),
              enable_poppler_qt4=$enableval,
              enable_poppler_qt4="try")
if test x$enable_poppler_qt4 = xyes; then
  PKG_CHECK_MODULES(POPPLER_QT4,
                    QtCoreE >= 4.7.0 QtGuiE >= 4.7.0 QtXmlE >= 4.7.0)
  PKG_CHECK_MODULES(POPPLER_QT4_TEST,
                    QtTestE >= 4.7.0)
elif test x$enable_poppler_qt4 = xtry; then
  PKG_CHECK_MODULES(POPPLER_QT4,
                    QtCoreE >= 4.7.0 QtGuiE >= 4.7.0 QtXmlE >= 4.7.0,
                    [enable_poppler_qt4="yes"],
                    [enable_poppler_qt4="no"])
  if test x$enable_poppler_qt4 = xyes; then
    PKG_CHECK_MODULES(POPPLER_QT4_TEST,
                    QtTestE >= 4.7.0,
                    [enable_poppler_qt4="yes"],
                    [enable_poppler_qt4="no"])
  fi
fi

at this point poppler-0.26.5-r0 do_configure works
but at do_compile I get the following linker error probably related to
some wrong Qt4 library setting:

Any Qt4 expert out there could give me a hint about how to solve this?

TIA
