Thanks for your help, indeed my build is using wrong cmake config files Build log is at [1]. It runs cmake as /home/qt/work/qt/qtwebkit -DPORT=Qt -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE=/home/qt/work/qt/qtwebkit/qmake_toolchain.cmake -DUSE_LIBHYPHEN=OFF -DCMAKE_PREFIX_PATH="/home/qt/work/install" Somehow config files from /home/qt/work/install are not picked.
