>>> [Use precompiled headers for VS]
Ah, here is the official request. ;)
First: Is it worth the effort? How big is the speedup?
I did a test. Use the attached config.h.cmake. Make a config.cpp file
with just one line:
#include "config.h"
in it.
Now, change all project files to use precompiled headers through
config.h (add /Yu"config.h" to command line for all .cpp files).
Finally, add the config.cpp file to your project, for instance lyx-qt4,
and make that generate the precompiled header (add /Yc"config.h" to the
command line instead of /Yu"config.h".)
Enjoy.
My compile times were halved.
Regards,
Asger
