I got a link error: `undefined reference to

by adding `--vverbose` dub option, I found the final expanded
link cmd is:
```
.../ldc2/bin/ldc2 ... -L-L/usr/local/cuda/lib64
-L-lcudart_static ...
```
This "-L-l" format does not look correct?
Then I changed the dub.json to :
```
"lflags": [
...
/usr/local/cuda/lib64/libcudart_static.a
...
],
```
then it links correctly.
I'm just wondering if the dub expansion "-L-l" format is a
bug? (but looks like this same expansion works for other
libraries?)
Thanks.
In the dub `libs:["mylibname_noext"]` +
`lflags:["-L/Path/to/lib"]`
In side: `-L-L/path -L-lmylibname_noext`.
If you need to pass a specific file (.o, .obj, .a, .lib) add in
`sourceFiles:["..."]`
The problem presented shows that this library possibly has other
dependencies.
Have you looked into the cuda community? I did a quick search and
saw a similar problem involving cuda12.
Unfortunately, I've never tried anything involving cuda. Sorry if
this doesn't answer properly.
