I've seen the same, many times. And KMail is not the only project with this 
issue afaik. I've seen this also in KDevelop land and also in Frameworks while 
it was still in flux. Now that it settled down on a stable API the issue is 
gone.

make uninstall && make install

Still sucks, but much faster than that.

While I understand your frustration, please note that that this is not a KMail 
specific issue - their CMake files are - afaik - not special or do anything 
wrong. Rather, it seems to be an issue in either CMake or how we use CMake in 
KDE. We should try to figure out the culprit and fix it together. I'm also 
CC'ing kde-buildsystem for that reason.
