QMAKE_CXX.LIBDIRS = \
    /usr/lib64/gcc/x86_64-suse-linux/4.8 \
    /usr/lib64 \
    /lib64 \
    /usr/x86_64-suse-linux/lib \
    /lib \
    /usr/lib

That comes from the system installed /usr/lib64/libqgsttools_p.prl
which was installed by the openSuse rpm  libqt5-qtmultimedia-devel-5.9.1

it contains:

QMAKE_PRO_INPUT = gsttools.pro
QMAKE_PRL_TARGET = libqgsttools_p.so.1.0.0
QMAKE_PRL_CONFIG = lex yacc depend_includepath testcase_targets import_plugins import_qpa_plugin qt_build_extra file_copies qmake_use qt warn_on release link_prl incremental shared release linux unix posix gcc sse2 sse3 ssse3 sse4_1 sse4_2 avx avx2 compile_examples enable_new_dtags f16c largefile nostrip prefix_build force_independent utf8_source create_prl link_prl prepare_docs qt_docs_targets no_private_qt_headers_warning QTDIR_build qt_example_installs exceptions_off testcase_exceptions explicitlib have_target dll c++11 thread uic opengl moc resources
QMAKE_PRL_VERSION = 1.0.0
QMAKE_PRL_LIBS = -L/usr/lib64 -L/home/abuild/rpmbuild/BUILD/qtmultimedia-opensource-src-5.9.1/lib -lQt5MultimediaWidgets -lQt5Multimedia -lQt5Widgets -lQt5Gui -lQt5Network -lQt5Core -lGL -lpthread -lasound -lgstaudio-1.0 -lgstvideo-1.0 -lgstpbutils-1.0 -lgstapp-1.0 -lgstbase-1.0 -lgstreamer-1.0 -lgobject-2.0 -lpulse-mainloop-glib -lpulse -lglib-2.0

Why does my Qt build use the system installed /usr/lib64/libqgsttools_p.prl file and not the one from the build dir
/home/PACKAGES/qt/5.9.1/qt-everywhere-opensource-src-5.9.1/qtmultimedia/lib/libqgsttools_p.prl
which contains
QMAKE_PRL_BUILD_DIR = /home/PACKAGES/qt/5.9.1/qt-everywhere-opensource-src-5.9.1/qtmultimedia/src/gsttools
QMAKE_PRO_INPUT = gsttools.pro
QMAKE_PRL_TARGET = libqgsttools_p.so.1.0.0
