I'm trying to build libvnc, and I have run into this when building other source code as well. For some reason cmake errors out when checking the dependency of a symlinked file, after executing 'cmake --build .'. I'm not sure I'm even describing that properly. It's best understood by looking at the below. This is the relevant section of the build.make file.
libvncclient.so.0.9.12: CMakeFiles/vncclient.dir/link.txt @$(CMAKE_COMMAND) -E cmake_echo_color --switch=$(COLOR) --green --bold --progress-dir=/home/bsferrazza/lfs/sources/libvncserver/build/CMakeFiles --progress-num=$(CMAKE_PROGRESS_10) "Linking C shared library libvncclient.so" $(CMAKE_COMMAND) -E cmake_link_script CMakeFiles/vncclient.dir/link.txt --verbose=$(VERBOSE) $(CMAKE_COMMAND) -E cmake_symlink_library libvncclient.so.0.9.12 libvncclient.so.1 libvncclient.so libvncclient.so.1: libvncclient.so.0.9.12 @$(CMAKE_COMMAND) -E touch_nocreate libvncclient.so.1 libvncclient.so: libvncclient.so.0.9.12 @$(CMAKE_COMMAND) -E touch_nocreate libvncclient.so And here's the terminal output.

Oddly, if I then run that same command in the shell, and re-run 'cmake --build .' it continues just fine. So why was that command not properly executed within the cmake file? Thanks, Ben
