I included /opt/env/lenny-ppc/usr/share/qt4 (which I belive to be the root of the Qt installation) in CMAKE_FIND_ROOT_PATH but the Qt libraries still wasn't detected. > Then, if you need to help it some more, you may set the path to the QtCore > library manually, or other variables manually. Managed to compile and link when I added the following snippet to the toolchain file: set(QT_HEADERS_DIR /opt/env/lenny-ppc/usr/lib) set(QT_LIBRARY_DIR /opt/env/lenny-ppc/usr/include/qt4) set(QT_QTCORE_LIBRARY /opt/env/lenny-ppc/usr/lib/libQtCore.so) set(QT_QTCORE_LIBRARY_RELEASE /opt/env/lenny-ppc/usr/lib/libQtCore.so) set(QT_QTCORE_INCLUDE_DIR /opt/env/lenny-ppc/usr/include/qt4) set(QT_QTDBUS_LIBRARY /opt/env/lenny-ppc/usr/lib/libQtDBus.so) set(QT_QTDBUS_LIBRARY_RELEASE /opt/env/lenny-ppc/usr/lib/libQtDBus.so) set(QT_QTDBUS_INCLUDE_DIR /opt/env/lenny-ppc/usr/include/qt4) set(QT_QTXML_LIBRARY /opt/env/lenny-ppc/usr/lib/libQtXml.so) set(QT_QTXML_LIBRARY_RELEASE /opt/env/lenny-ppc/usr/lib/libQtXml.so) set(QT_QTXML_INCLUDE_DIR /opt/env/lenny-ppc/usr/include/qt4) Would have been nice if I didn't have to set those paths explicitely. Will continue the digging. > If lib/qt4 is another path that should be searched automatically, let us > know, and we can add it to FindQt4.cmake. My bad, the usr/lib/qt4 directory only contains the plugins dir.
