|
||
Meson is an open source build system meant to be both extremely fast, and,
|
||
even more importantly, as user friendly as possible.
|
||
|
||
The main design point of Meson is that every moment a developer spends
|
||
writing or debugging build definitions is a second wasted. So is every
|
||
second spent waiting for the build system to actually start compiling
|
||
code.
