meson - Meson build element

This is a BuildElement implementation for using Meson build scripts.

You will often want to pass additional arguments to meson. This should be done on a per-element basis by setting the meson-local variable. Here is an example:

variables:
  meson-local: |
    -Dmonkeys=yes

If you want to pass extra options to meson for every element in your project, set the meson-global variable in your project.conf file. Here is an example of that:

elements:
  meson:
    variables:
      meson-global: |
        -Dmonkeys=always

Here is the default configuration for the meson element in full:

# Meson default configuration

variables:

  build-dir: _builddir

  # Project-wide extra arguments to be passed to `meson`
  meson-global: ''

  # Element-specific extra arguments to be passed to `meson`.
  meson-local: ''

  # For backwards compatibility only, do not use.
  meson-extra: ''

    --sbindir=%{sbindir} \
