I confirm clang compiles well now. Thanks Fabian.
(In reply to Askar Bektassov from comment #2) > I confirm clang compiles well now. Thanks Fabian. Sorry i meant cmake
@kde team: please approve the fix from comment #1, this is broken on macOS systems, cmake is necessary for Clang, the main compiler on macOS. Thanks!
The problem still exists on dev-util/cmake-3.11.1, although the issue can be promptly solved with the fix proposed by Fabian.

Is the workaround still needed in more recent CMake versions?
