Fixes: #8210 Following changes has been made to ensure correct behavior on different system: - Python script to detect changes to directories, including empty ones. When files are modified the list is updated If sub-directories are added / removed a trigger file is touched to notify cmake to re-run - Windows: To detect changes to header files in include for parse_syscalls.py all files must be individual monitored. Hence all headers are globbed added to dependencies. CMake configure depends on the folders so the added / removed files are picked up. - Other: Folders are monitored through the python list file so that added / remove / modified Added / removed sub-directories are detected through trigger file in order to re-run cmake.
