# that is required by the codebase. This is to avoid sprinkling cflags all over
# the places, which is very fragile especially for our codebase that needs to
# deal with several build systems.
# The way this works is the following:
# - This rule generates a header that contains a bunch of lines like:
# #define PERFETTO_BUILDFLAG_DEFINE_PERFETTO_ANDROID_BUILD()
# - The generated header is included by base/build_config.h
# - Source files in the codebase #include base/build_config and use the
# pattern #if PERFETTO_BUILDFLAG(PERFETTO_ANDROID_BUILD)
