make VERBOSE=1 doesn't show such information for me (even after unaliasing "make", i.e. using /usr/bin/make) -laptop- dfaure 19:42 /devel/kde/build/4/kdelibs4_cmake>/usr/bin/make VERBOSE=1 /devel/other/inst/bin/cmake -H/devel/kde/src/4/kdelibs -B/devel/kde/build/4/kdelibs4_cmake --check-build-system CMakeFiles/Makefile.cmake 0 [...] -- Configuring done -- Generating done -- Build files have been written to: /devel/kde/build/4/kdelibs4_cmake /usr/bin/make -f CMakeFiles/Makefile2 all make[1]: Entering directory `/devel/kde/build/4/kdelibs4_cmake' /usr/bin/make -f dcop/CMakeFiles/DCOP.dir/build.make dcop/CMakeFiles/DCOP.dir/depend [...] make[2]: Entering directory `/devel/kde/build/4/kdelibs4_cmake' Building CXX object kdecore/CMakeFiles/kdecore.dir/kapplication.o ...
