#
# CMake function to imitate Bazel's cc_library rule.
#
# 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}.
# This is to reduce namespace pollution.
#
# absl_cc_library(
# NAME
# awesome_lib
# HDRS
# "a.h"
# SRCS

# )
# absl_cc_library(
# NAME
# fantastic_lib
# SRCS
# "b.cc"
# DEPS
# absl_internal_awesome_lib # not "awesome_lib"!
# )
#
# If PUBLIC is set, absl_cc_library will instead create a target named
# absl_${NAME} and an alias absl::${NAME}.
#
# absl_cc_library(
# NAME
# main_lib
# ...
# PUBLIC
# )
#
# User can then use the library as absl::main_lib (although absl_main_lib is defined too).
