在递归下编译目录下的所有cpp文件

Question

我正在编写一个用于在Android中编译jni代码的make文件。 我希望能够递归地编译驻留在特定文件夹下的所有cpp文件。

我该怎么做？ 我试图玩通配符命令，但没有得到我需要的结果。

Android make系统有一个gmake宏来处理这个问题。请参阅NDK中的文档doc\ANDROID-MK.html。这里是摘录：

all-subdir-makefiles 
    Returns a list of Android.mk located in all sub-directories of 
    the current 'my-dir' path. For example, consider the following 
    hierarchy: 

    sources/foo/Android.mk 
    sources/foo/lib1/Android.mk 
    sources/foo/lib2/Android.mk 

    If sources/foo/Android.mk contains the single line: 

    include $(call all-subdir-makefiles) 

    Then it will include automatically sources/foo/lib1/Android.mk and 
    sources/foo/lib2/Android.mk 

    This function can be used to provide deep-nested source directory 
    hierarchies to the build system. Note that by default, the NDK 
    will only look for files in sources/*/Android.mk
