salve,
i am using cmake to build compiz but it breaks with the cmake switch -DCMAKE_UNIT_BUILD=TRUE.
a very good and short description how does unity build are work: https://mesonbuild.com/Unity-builds.html
```

salve,
i am using archlinux and with cmake to build compiz but it breaks with the cmake switch -DCMAKE_UNIT_BUILD=TRUE.
a very good and short description how does unity build are work: https://mesonbuild.com/Unity-builds.html
as build time example for a successful unity build or jumbo build. i tested this feature with kactivities three times and it reduce the build time greatly!
#with set `-DCMAKE_UNITY_BUILD=true`
real 66,03 - 68,91 - 68,93
user 92,77 - 98,05 - 68,93
sys 8,80 - 8,76 - 8,95```
#without `-DCMAKE_UNITY_BUILD=true`
real 128,53 - 125,27 - 129,16
user 219,17 - 215,70 - 219,40
sys 15,54 - 15,68 - 16,41
unfortunale compiz isn't in the arch repository and i must rebuild every time when something is changed and i don't "speak" c++ so it isn't possible to fix this problem :( |
