meson setup panics in CUDA project

[JackDyre]

Describe the bug
In a pure CUDA project that links an executable built target with a static library build target, meson setup panics if 'c' is not declared as a language in the project() along with 'cuda'

Declaring 'c' as one of the project languages makes it behave just fine.

Removing the static library build target and only compiling main.cu as a normal cuda executable makes it behave just fine.

To Reproduce

   ~/../../meson_repro ❯ ls --tree
.
├── kernels.cu
├── main.cu
└── meson.build

project(
    'meson_repro',
    # 'c',
    'cuda',
    default_options: ['warning_level=3'],
)

kernels_lib = static_library('kernels', 'kernels.cu')

executable('ml', 'main.cu', link_with: [kernels_lib])

   ~/../../meson_repro ❯ meson setup out

    This is a Meson bug and should be reported!

Expected behavior
Not to panic.

• Arch Linux x86_64
• meson 1.7.0
• python 3.13.2
• ninja 1.12.1

I was able to reproduce this from the the most recent commit as well as the official arch linux package

I was unable to find a good commit as to bisect from.

But, if it is helpful:

I was able to bisect to find that 0240d760c7699a059cc89e584363c6431cdd2b61 is the first commit that gives the same error message that the most recent version has.

Before this commit I found many different error messages. I did not respect MSPV when poking around for a good bisection commit. To test the different versions, I just did ../meson/meson.py from my dummy repro project.
