demo４示例 链接第三方动态库，静态库。
使用cc_import链接外部库。原理是通过cc_import规则导入第三方库，然后cc_binary再依赖cc_import规则的target，也即依赖第三方库。

├── shared_lib
│ ├── BUILD 动态库的目标名必须写成libfoo.so的形式
│ ├── func.c
│ └── func.h

│ ├── BUILD 静态库的目标名可以省略lib*.a

└── WORKSPACE
先分别将shared_lib和static_lib生成对应的动态库和静态库，然后在link包中链接这两个库，最后有main.c调用库中的API。
static_lib BUILD
cc_library(
name = "static",
srcs = ["static.c"],
hdrs = ["static.h"],
linkstatic = True,
)
shared_lib BUILD
cc_binary(
name = "libfunc.so",
#name = "func",#必须写成libfunc.so,否则编译不过
srcs = ["func.h","func.c"],
linkshared = True,
)
link BUILD
cc_import(
name = "func",
hdrs = ["include/func.h"],
shared_library = "lib/libfunc.so",
)
cc_import(
name = "static",
hdrs = ["include/static.h"],
static_library = "lib/libstatic.a",
)
cc_binary(
name = "link_static_shared",
srcs = ["main.c"],
deps = [":func",":static"],
copts = ["-Ilink/include"],
)
