[poppler] qt5 and autotools help

[Albert Astals Cid]

Anyone with some autotools knowledge could check why the autotools build of the qt5 branch (with qt5 installed) fails?

The cmake build works fine. I tried comparing the compiler options passed but didn't find anything obviously different.

I'm getting
  CXXLD    test-poppler-qt5
../../qt5/src/.libs/libpoppler-qt5.so: undefined reference to `QVectorData::reallocate(QVectorData*, int, int, int)'
../../qt5/src/.libs/libpoppler-qt5.so: undefined reference to `QByteArray::realloc(int)'
../../qt5/src/.libs/libpoppler-qt5.so: undefined reference to `vtable for Poppler::OptContentModel'
../../qt5/src/.libs/libpoppler-qt5.so: undefined reference to `QString::fromAscii(char const*, int)'
