c++ - 包含其他库的 CMake add_library

Question

我正在设计一组可以在我的其他 C++ 项目中链接的库。为了使馆藏易于使用，我希望能够链接到各个图书馆，或者链接到一个包含所有其他图书馆的主图书馆。我如何在 CMakeLists.txt 文件中指定它？

例如:

add_library(library1 SHARED
    file1.cpp
    file2.cpp
)

add_library(library2 SHARED
    file3.cpp
    file4.cpp
)

# Define a master library that contains both of the others
add_library(master_library SHARED
    library1
    library2
)

是否有合适的方法通过 CMake 获得此功能？

编辑:

此问题不是以下问题的重复:CMake: Is it possible to build an executable from only static libraries and no source?

这只与共享库有关，与静态库或可执行文件无关。

Answer 1

这个解决方案似乎有效。

add_library(library1 SHARED
    file1.cpp
    file2.cpp
)

add_library(library2 SHARED
    file3.cpp
    file4.cpp
)

# dummy file is required to avoid a cmake error, but this
# "dummy" file serves no other purpose and is empty.
add_library(master_library SHARED
    dummy.cpp
)

# Link the master library with the other libraries
target_link_libraries(master_library
    library1
    library2
)

完成此操作后，我能够仅使用 master 库编译和链接代码。
