[ros-dev] Does CMake take longer than rbuild

[Timo Kreuzer]

Hi,

One of the reasons why CMake is slower is that if does full dependency 
checking.
If you enabled this feature in rbuild, a clean build was extremely slow.

90% of the time I don't do full builds, but just rebuild a module.
For that you can use "make foo/fast", which will be much faster than 
ever possible with rbuild.

If you you want to get much higher build speed and have no problem with 
using an experimental system,
you can try ninja. It replaces make and is incredibly fast. You need a 
special CMake version
for that though.

Regards,
Timo
