[Qt] Automate the use of AllInOne files in the Qt build
Created attachment 162207 [details]
With this feature enabled even on a Linux release build the size of the library shrinks by a whole megabyte. I'm wondering if we should enable this by default perhaps.
Right now it is the default on Windows and Mac debug builds, but in theory there is a positive impact on release builds, too. Increased visibility to the compiler reduces the need for link time optimization support in the toolchain.
FWIW the use of all-in-one files _is_ required for a debug build on Windows. Even with the current use of just SVGAllInOne.cpp we end up with a library that's too big for MSVC 2008 at least to handle. Adding for example AcessibilityAllinOne.cpp gets us juuust below the limit again, but I think we might as well take as much as we can get :)
