- remove CLANG env, as it might be confused for the compiler. And it doesn't fit the build system that well anyway. (as we're compiling based on file extension already) - locate source files using find, rather than a bunch of wildcards. - rename TARGET to BIN and store DIR_BIN and DIR_OBJ for the output directories - use pattern matchin for C object file creation, rather than specifying all the sources manually - remove directory target as directory creation is handled by the recipe's themselves now.
