May I ask, whether you have tried to use Dub, or is s.th. blocking
you from using Dub?

Kind regards

It's very odd to me that Manjaros pkg-config doesn't include that pkg-config path by default and also doesn't include that library path by default, every distro I've so far used did that.

Can you show us your meson.build? You need to set `dependencies:` properly to include all dependencies so ninja includes the right dirs and links the required libraries. You can look at other projects using D for that, e.g. I do it like this: https://github.com/Cogitri/corecollector/blob/master/source/corectl/meson.build

I tested dub and it fetched and compiled mir.ndslice and lubeck without issues. Then somebody mentioned meson and that it gives you more control and speed over the build. I also saw that mir library uses meson so decided to give it a try.

You can look at other projects using D for that, e.g. I do it like this: https://github.com/Cogitri/corecollector/blob/master/source/corectl/meson.build

Here is my meson.build file
---------------------------
project('demo_proj', 'd',
  version : '0.1',
  default_options : ['warning_level=3']
  )

mir_alg = dependency('mir-algorithm', method: 'pkg-config')
lubeck = dependency('lubeck', method: 'pkg-config')
required_deps = [mir_alg, lubeck]

ed = executable('demo_proj', 'app.d', dependencies: required_deps, install : true)


As I mentioned earlier cblas.d is installed in /usr/local/include/d/cblas/cblas/cblas.d

If I replace lubeck with mir-lapack (which I also installed into /usr/local/lib), repeat "meson build && cd build && ninja" and call ./demo_proj, I get this:
-----
./demo_proj: error while loading shared libraries: subprojects/mir-algorithm/libmir-algorithm.so.3.4.0:ject file: No such file or directory

But libmir-algorithm.so.3.4.0 is installed in /usr/local/lib and it is in $PATH :(

Seems like you have missed the *.wrap files in subprojects folder. It's a bad idea to install D meson libs into system as probably you will want to control versions easily.

You need all *wrap files recursively.
Check this https://github.com/kaleidicassociates/lubeck/tree/master/subprojects
and add a wrap file for Lubeck.
You can specify tags instead of the master branches. - it is recommended for stable work.
