Bug 235459 – WebKit fails to build - error: 'webrtc/rtc_base/network.h' file not found

• Component: Platform
• Status: RESOLVED FIXED

[Michael Saboff]

When building with a SYSTEM_CONTENT_PATH, we can fail when building WebKit:

.../Source/WebKit/Shared/RTCNetwork.h:32:10: fatal error: 'webrtc/rtc_base/network.h' file not found
#include <webrtc/rtc_base/network.h>
         ^~~~~~~~~~~~~~~~~~~~~~~~~~~

I'm not super familiar with the plumbing of all the settings variables, but this patch LGTM.

Why is this "s/\/$//" needed?

nit: call this SYMLINK_TARGET instead?

Can't you do this just once outside of the for loop?  The only difference is that moving this out would create this directory even if HEADER_FOLDER_LIST is empty.  But we know it'll never be empty, right?

Ditto.  Do this outside the for loop?

To eliminate any trailing '/'.

This follows some the name of other similar scripts.

I moved both of these to above the loop.
