Makefileテンプレート(改良)

Makefileテンプレート:1)モジュールファイル(main関数を含まない)は、src/xxxディレクトリの下に分類されます.例えば、src/conf/conf.c;src/util/pool.c 2)共通ヘッダファイルはsrc/includeディレクトリに格納、モジュールプライベートヘッダファイルはモジュールディレクトリsrc/xxxディレクトリの下3)mainエントリポイントを含むすべてのソースコードファイルはsrc/ディレクトリの下、例えばsrc/main.c, src/test.cなど.4)カスタムターゲットを追加することをサポートし、自分のターゲットを定義することで実行可能ファイルをコンパイルすることができる(テンプレートの最後の例を参照).bin/main,bin/testなど.5)依存自動導出をサポートする.6)使用時は、変数:CC、LINK、SRC_をご自身で修正してくださいFILE_TYPE、 MAIN_FILE、 SRC_MODULES、 LIBS、 INCLUDE_PATHでいいです.
