# This file is in a separate directory so all targets in the build can refer to
|
|
# the buildflag header to get the necessary preprocessor defines without
|
|
# bringing in any CEF targets. Other targets can depend on this target
|
|
# regardless of whether CEF is being built. Set the `enable_cef=false` GN arg to
|
|
# disable the CEF changes when building Chrome.
|
|
#
|
|
# Example usage:
|
|
#
|
|
# 1. An existing GN configuration file at path/to/foo/BUILD.gn:
|
|
#
|
|
# # Import the `enable_cef` arg.
|
|
# import("//cef/libcef/features/features.gni")
|
|
# ...
|
|
#
|
|
# # An existing target that is modified for CEF.
|
|
# # The target type might instead be `component`, `source_set`, etc.
|
|
# static_library("foo") {
|
|
# sources = [ ... ]
|
|
#
|
|
# deps = [
|
|
# # Always include the CEF features.
|
|
# "//cef/libcef/features",
|
|
# ...
|
|
# ]
|
|
#
|
|
# if (enable_cef) {
|
|
# # Actions to perform when the CEF build is enabled.
|
|
#
|
|
# # Optionally include CEF source files directly in this target. This
|
|
# # approach is required for targets that are either directly or
|
|
# # indirectly included in a `component` target (otherwise
|
|
# # `is_component_build=true` builds will fail). Keep in mind that these
|
|
# # files are part of this target instead of the `libcef_static` target
|
|
# # and therefore subject to any target-specific configuration settings
|
|
# # such as include paths, defines, compiler flags, etc.
|
|
# sources += [
|
|
# "//cef/libcef/browser/foo_helper.cc",

|
|
# configs += [ "//cef/libcef/features:config" ]
|
|
# }
|
|
# ...
|
|
# }
|
|
#
|
|
# 2. An existing C++ source file at path/to/foo/foo.cc:
|
|
#
|
|
# // Include the `BUILDFLAG(ENABLE_CEF)` definition.
|
|
# #include "cef/libcef/features/features.h"
|
|
# ...

# // Chrome headers here...

# #endif
