如何使用'CMakeLists.txt‘中的add_library将整个文件(.cpp、.h等)包含在目录中

Question

在我的项目中，我使用cpp和.h文件，它们都在不同的文件夹中

|-src
  |-main
   |-java
   |-cpp
    |-native-lib.cpp
    |-library-1
      |-include
        |-lib11.h
        |-lib12.h
        |-... 
    |-library-2
      |-include
        |-lib21.h
        |-lib22.h
        |-... 

在当前版本中，我将每个文件添加到'CMakeLists.txt'中

...

add_library(# Sets the name of the library.
            native-lib

            # Sets the library as a shared library.
            SHARED

            # Provides a relative path to your source file(s).



            src/main/cpp/native-lib.cpp
            src/main/cpp/library-1/include/lib10.h
            src/main/cpp/library-1/include/lib11.h
            src/main/cpp/library-1/include/lib12.h
            src/main/cpp/library-1/include/lib13.h
            ...

            src/main/cpp/library-2/include/lib21.h
            src/main/cpp/library-2/include/lib22.h
            src/main/cpp/library-2/include/lib23.h
            ...

)

我试着像下面这样添加

...

add_library(# Sets the name of the library.
            native-lib

            # Sets the library as a shared library.
            SHARED

            # Provides a relative path to your source file(s).



            src/main/cpp/native-lib.cpp
            src/main/cpp/library-1/include/*.h  #expected result: it  will include all '.h' files in directory, but gradle sync failed

            src/main/cpp/library-2/include/*.h#expected result: it  will include all '.h' files in directory, but gradle sync failed


)
...

使用add_library包含文件夹中所有文件的任何其他方式

您可以生成源文件的列表：

file(GLOB SOURCES "src/*.h")

现在，SOURCES变量可以用作add_library中的参数。

add_library(native-lib SHARED ${SOURCES})
