It has come to my attention that hedgewars uses Qt5 private apis, and was hit was broken dependencies due to a recent update,
https://bodhi.fedoraproject.org/updates/FEDORA-2018-bea1e0b465

So, 2 things:

1.  Due to private api usage, please add these to hedgewars.spec to help track it and avoid issues in the future:

BuildRequires: qt5-qtbase-private-devel
%{?_qt5:Requires: %{_qt5}%{?_isa} = %{_qt5_version}}

2.  BuildRequires: qt5-devel
That is a metapackage for end-users only.  KDE-SIG strongly recommends (as strongly as is possible) to not use this metapackage in official packaging.  Please remove that and use modular dependencies instead as appropriate, ie, something like:
BuildRequires: qt5-qtbase-devel
BuildRequires: qt5-qtdeclarative-devel
...


I'll work on creating a pull request to implement both of these changes.
