Hi,
I just switched from 2.06 to 2.4.2
and noticed that compilation time increased considerably - which is
annoying.
In particular when nothing has changed the "nothing to do" build now
takes >> 60 seconds.
With 2.06 it took < 5 seconds as expected to build when everything was
up to date.
The problem seems to be:
Although nothing has changed
cmake configures, generates and writes toplevel build files
for every library target on each build.
I expected it only on teh first cmake run or if any of the files (e.g.
CmakeListst.txt) changed.
This consumes a lot of time.
I am actually testing on Windows with Visual Studio .net 2003.
(Linux will follows in the next days...)
(1) Any ideas what may be going wrong?
Jan.
