3，问题，难道就没有问题？ 1，cmake 很简单，但绝对没有听起来或者想象中那么简单。 2，cmake 编写的过程实际上是编程的过程，跟以前使用 autotools 一样，不过你需要编 写的是 CMakeLists.txt(每个目录一个) ” ，使用的是 cmake ” 语言和语法 。 3，cmake 跟已有体系的配合并不是特别理想，比如 pkgconfig，您在实际使用中会有所 体会，虽然有一些扩展可以使用，但并不理想。 t1 在 t1 目录建立 main.c 和 CMakeLists.txt(注意文件名大小写)： main.c 文件内容： //main.c #include int main() { printf(“Hello World from t1 Main!\n”); return 0; } CmakeLists.txt 文件内容： PROJECT (HELLO) "${HELLO_SOURCE_DIR}) ADD_EXECUTABLE(hello SRC_LIST) 2，开始构建 所有的文件创建完成后，t1 目录中应该存在 main.c 和 CMakeLists.txt 两个文件 接下来我们来构建这个工程，在这个目录运行： cmake . (注意命令后面的点号，代表本目录)。 输出大概是这个样子： -- Check for working C compiler:
