Subject: [bug#75966] [PATCH v3 01/10] gnu: qtwebengine: Fix default path for QtWebEngineProcess.
Date: Sun,  2 Feb 2025 12:34:50 +0800

From: 宋文武 <iyzsong <at> member.fsf.org>

Since qtwebengine and qtbase are not installed into the same prefix,
the default path for QtWebEngineProcess won't work.  Fix it so that
we no longer need to set QTWEBENGINEPROCESS_PATH anymore.

* gnu/packages/qt.scm (qtwebengine-5, qtwebengine)[arguments]:
Substitute 'QLibraryInfo::LibraryExecutablesPath' in 'substitute-source phase.
[native-search-paths]: Remove QTWEBENGINEPROCESS_PATH.
* guix/build/qt-utils.scm (variables-for-wrapping): Remove
QTWEBENGINEPROCESS_PATH.
