Hi, Rosegarden fails to build, at least on first attempt, with
cmake-3.9.0 which has just hit openSUSE:Factory:

If you use make -j2 or greater then src/svnversion.h is built but it
still fails on first attempt and then the next make succeeds.
I've dug around but I can't see what's missing. The only extra files
after a make -j2 are src/svnversion.h and src/svnversion.h.txt.
I've worked around this with "make -j4 || make -j4"
After really examining the difference between 3.9.0 and 3.5.2 I suspect
that it's a cmake bug. I now execute make svnheader prior to make -jx
