[Interest] QWE 5.9.3/Linux: chromium/crypto build trips over headers from the installed system openssl

[René J.V. Bertin]

Hi,

As mentioned in another post, I'm running into a build failure due to a conflict between WE's boringssl and the installed openssl headers: see the build log extract below.

I do not see any obvious configuration options to use either boringssl or the system openssl; google suggests that this could be done through patching but before the "move to gn". 

I don't remember having this issue while building QWE 5.8.0 a couple of months ago. 

Any ideas?
Thanks,
R.
