BuildSystem

What is needed from the build system?

• Simplicity

  • Declarative programming is best - just tell what you want to get and let the buildsystem figure out the rest.

• Sub-directories/sub-projects support

  • With possibility to infer settings from subproject into a dependency (much like uselib in waf)
  • Subprojected must be able to poke at parent's environment and use it by default.

• Parallel execution

  • Tasks must be extremely parallelizable. Everything that is not dependent on a particular result must be possible to run, fully utilizing available cores.

• Custom tasks support

  • Should be easy to specify dependencies of a custom task and how to run it when they are satisfied.

• Cross-platform building

  • Should be possible to easily build from same sources a set of different resulting binaries, including cross-tools building for other architectures.

• Config file generation for a specific configuration

  • Should support cross-platform building

• Out-of-source-directory builds
