How to compile chromium with additional flags?

I am going to instrument Chromium. So, after adding some tracepoints, I have to add some additional flags during compilation of Chromium but I do not know where I should add them exactly! Do you have any idea how I can compile chromium with the debugging flag for chromium?

Thanks

To get Chromium to respect custom CXX, CXXFLAGS, LDFLAGS etc. settings, whether for instrumentation or for any other flags you wish to add, override the toolchain.

Quoting from https://chromium.googlesource.com/chromium/src/+/lkgr/build/toolchain/linux/unbundle/:

Usage

Add the following to GN args:

custom_toolchain="//build/toolchain/linux/unbundle:default"
host_toolchain="//build/toolchain/linux/unbundle:default"

See more docs on GN.

To cross-compile (not fully tested), add the following:

host_toolchain="//build/toolchain/linux/unbundle:host"
v8_snapshot_toolchain="//build/toolchain/linux/unbundle:host"

Note: when cross-compiling for a 32-bit target, a matching 32-bit toolchain may be needed.
