#
|

# 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
|
||||
# VISIBILITY_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 -DBUILD_TESTING=ON to CMake.
|
||||
#
|
||||
# Note:
|
||||
#
|
||||
# By default, absl_cc_library will always create a library named absl_${NAME},
|
||||
# which means other targets can only depend this library as absl_${NAME}, not ${NAME}.
|
||||
# This is to reduce namespace pollution.
