[Interest] Qt 5.4.0: building qtwebengine out-of-tree?

[Becsi Andras]

Hi René,

It is only possible to build QtWebEngine out-of-tree with a developer build of Qt, especially on OS X.
If the module itself builds, you could try removing the QTWEBENGINE_BUILD_PARTS lines in qtwebengine.pro, and build them after you installed the QtWebEngine module.
