# To build a static library example.a from example.cc using the system
#  compiler (like GCC):
#
#   cc_library(example SRCS example.cc)
#
# To build a static library example.a from multiple source files
# example{1,2,3}.cc:
#
#   cc_library(example SRCS example1.cc example2.cc example3.cc)
#
# To build a shared library example.so from example.cc:
#
#   cc_library(example SHARED SRCS example.cc)
#
# To build a library using Nvidia's NVCC from .cu file(s), use the nv_
# prefixed version:
#
#   nv_library(example SRCS example.cu)
#
# To specify that a library new_example.a depends on other libraies:
#
#   cc_library(new_example SRCS new_example.cc DEPS example)
#
# Static libraries can be composed of other static libraries:
#
#   cc_library(composed DEPS dependent1 dependent2 dependent3)
#
# To build an executable binary file from some source files and
# dependent libraries:
#
#   cc_binary(example SRCS main.cc something.cc DEPS example1 example2)
#
# To build an executable binary file using NVCC, use the nv_ prefixed
# version:
#
#   nv_binary(example SRCS main.cc something.cu DEPS example1 example2)
#
# To build a unit test binary, which is an executable binary with
# GoogleTest linked:
#
#   cc_test(example_test SRCS example_test.cc DEPS example)
#
# To build a unit test binary using NVCC, use the nv_ prefixed version:
#
#   nv_test(example_test SRCS example_test.cu DEPS example)
#
# It is pretty often that executable and test binaries depend on
# pre-defined external libaries like glog and gflags defined in
# /cmake/external/*.cmake:
#
#   cc_test(example_test SRCS example_test.cc DEPS example glog gflags)
#
# To build a go static library using Golang, use the go_ prefixed version:
#
#   go_library(example STATIC)
#
# To build a go shared library using Golang, use the go_ prefixed version:
#
#   go_library(example SHARED)
