Hi! I'm not able to compile KDevelop4 with Debian Testing (workaround below)
Here is a complete CMakeList.txt to reproduce the issue. #> cat CMakeLists.txt project(demo) cmake_minimum_required(VERSION 2.8) find_package(Qt4 COMPONENTS QtWebKit REQUIRED ) message(STATUS "Test status" ${QT_QTWEBKIT_FOUND} ${QT_QTWEBKIT_INCLUDE_DIR} ${QT_QTWEBKIT_LIBRARY}) Looks like the issue is related to multi-arch support in libqtwebkit-dev because libQtWebKit.so is missed from /usr/lib/x86_64-linux-gnu #> dpkg -L libqtwebkit-dev | grep '/usr/lib' /usr/lib /usr/lib/pkgconfig /usr/lib/pkgconfig/QtWebKit.pc /usr/lib/libQtWebKit.prl /usr/lib/qt4 /usr/lib/qt4/plugins /usr/lib/qt4/plugins/designer /usr/lib/qt4/plugins/designer/libqwebview.so /usr/lib/libQtWebKit.so #> dpkg -l libqtwebkit-dev ii libqtwebkit-dev 2.2.0-3 Web content engine library for Qt - development files The following workaround 'fixes' the issue until the package is really fixed: #> sudo ln -s /usr/lib/libQtWebKit.so /usr/lib/x86_64-linux-gnu Hopefully it helps to fix the issue.
