+# CMake function to imitate Bazel's cc_library rule.

+# DEPS: List of other libraries to be linked in to the binary targets
+# COPTS: List of private compile options

+# LINKOPTS: List of link options
+# PUBLIC: Add this so that this library will be exported under absl:: (see Note).

+# TESTONLY: When added, this target will only be built if user passes -DABSL_RUN_TESTS=ON to CMake.

+# By default, absl_cc_library will always create a library named absl_internal_${NAME},
