+# Parameters:
+# NAME: name of target (see Note)
+# HDRS: List of public header files for the library
+# SRCS: List of source files for the library
+# DEPS: List of other libraries to be linked in to the binary targets
+# COPTS: List of private compile options
+# DEFINES: List of public defines
+# 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.
+#
+# Note:
+#
+# By default, absl_cc_library will always create a library named absl_internal_${NAME},
+# which means other targets can only depend this library as absl_internal_${NAME}, not ${NAME}.
