KDiff3 1.8 release.

[Wolfgang Bauer]

The latest change 
(https://cgit.kde.org/kdiff3.git/commit/?id=638bd5a02893dde4a1927abd0c8a611b3b3ab6a1)  
unfortunately breaks the build here:

/usr/lib/gcc/i586-suse-linux/8/../../../../i586-suse-linux/bin/ld: 
CMakeFiles/kdiff3part.dir/pdiff.cpp.o: in function 
`debugLineCheck(Diff3LineList&, int, e_SrcSelector)':
/home/abuild/rpmbuild/BUILD/kdiff3-1.7.95git/src/pdiff.cpp:82: undefined 
reference to `kdeMain()'
/usr/lib/gcc/i586-suse-linux/8/../../../../i586-suse-linux/bin/ld: 
/home/abuild/rpmbuild/BUILD/kdiff3-1.7.95git/src/pdiff.cpp:96: undefined 
reference to `kdeMain()'
...
and so on.

Kind Regards,
Wolfgang
