# - Remove automagic dependency for coverage report generation tools
# - Fix Xig-0 automagic resolving('CMake Warning at tests/integration/xig/CMakeLists.txt:30 (message): Xig not found, you will not be able to run X Server integration tests')
# - Check proper compilation with missing gettext/intltool
# - CFLAGS are NOT respected, this needs to be fixed
# - Default decorator exec command in ccsm is bad
# - Check all dependencies once more
# - Check CMakeFiles.txt this subdirectories :
