相同的库名称在不同的子目录中：在父级调用`add_subdirectory`时冲突

Question

简单的文件夹结构就像

Root
    CMakeLists.txt
    SubA
        CMakeLists.txt
        some files to be built...
    SubB
        CMakeLists.txt
        some files to be built...

假设我分别在add_library(SubDirLib fooX.cpp)和SubA/CMakeLists.txt中都拥有SubB/CMakeLists.txt，其中X分别是A和B，那么如何在其中链接两个库SubA/SubDirLib和SubB/SubDirLib Root/CMakeLists.txt？请注意，如果我拨打电话，它将名称冲突

add_subdirectory(SubA)
add_subdirectory(SubB)

在Root/CMakeLists.txt

中
