Build problem with 4.8.0

[aga]

I'm trying to build 4.8.0 from git and am having problems.  I thought,
perhaps wrongly, that 4.8.0 would be KDE4 rather than qt5, but found
there were quite a few qt5 files involved.  Finally, I think I've got
rid of those and have now got to make.  I'm getting an error here that I
don't understand -

[  0%] Building CXX object
libkgpgfile/CMakeFiles/kgpgfile.dir/kgpgfile.cpp.o
In file included from
/home/aga/kmymoney-4.8.0/libkgpgfile/kgpgfile.cpp:20:0:

Now, I do seem to have that file in that directory, so what is the
problem, please.

Thanks
