Bug 395926

I attempted to build falkon on macOS primarily for updating MacPorts' qupzilla entry (cf. https://github.com/macports/macports-ports/pull/2020). Using macOS 10.13.5 with Xcode 9.4.1 (Apple LLVM version 9.1.0/clang-902.0.39.2), Qt 5.10.1 from MacPorts, extra-cmake-modules 5.29.0, and ki18n 5.47.0. Note: I changed where CMake was looking for Info.plist (cf. https://phabricator.kde.org/D13736).


Both falkon 3.0.1 and the current master branch (034365355a3eac8144453fd67ef184a4b601e4c2) fail to build due to errors compiling mocs_compilation.cpp.o:

Here's the full build log for 3.0.1 (as run from MacPorts w/ trace mode enabled): https://gist.github.com/chrstphrchvz/cc5979a7ab5f807fbad47eba3fb0a9ce
