For example:
configure --enable-board=common_pc \
          --enable-kernel=standard \
          --enable-rootfs=glibc_small \
          --enable-bootimage=iso \
          --enable-target-installer=yes \
          --with-installer-target-build=/home/user/my_project
Should be:
configure --enable-board=qemux86-64 \
          --enable-kernel=standard \
          --enable-rootfs=wr-installer \
          --enable-bootimage=iso \
          --enable-target-installer=yes \
          --with-installer-target-build=/home/user/my_project
