[cmake-developers] copy-if-changed in "make install"

[Alexander Neundorf]

Hi,

http://bugs.kde.org/show_bug.cgi?id=132074

Thomas complains that "make install" takes too long because cmake installs 
only if the files differ. So he implemented in unsercmake a version which 
doesn't compair the file contents, but only the size and the mtime.

This will undoubtedly work faster.
It will also install files which were only touched but haven't changed. 

What do you think of this ?

Bye
Alex
