Why does meson.project_source_root return nothing, instead of the promised absolute dir path?

Here's my problem in a nutshell, when my script does meson setup .build/debug:

Error message:

• meson.build:3:39: ERROR: Search directory .wi/build/WickedEngine is not an absolute path.

Despite doing:

• meson.get_compiler('cpp').find_library(dirs: [meson.project_source_root().join('.wi/build/WickedEngine')], .....)

As shown here:

What am I doing wrong here? Meson v1.6.1 for the record =)

"join" is not the same as Python's os.path.join, it's the same as String.join. You have

meson.project_source_root().join('foo')

After listify-ing the arguments:

meson.project_source_root().join(['foo'])

And this is just 'foo'.

Instead you want

meson.project_source_root() / 'foo'

Much obliged, thx! Somehow missed that / feature =)
