Hi,
Thanks for your review!

> Could you show how to test it?
Currently if I just run `vulkaninfo`, this error appears:
```
ERROR at /tmp/guix-build-vulkan-tools-1.3.280.0.drv-0/source/vulkaninfo/./
vulkaninfo.h:412: Failed to initialize: Vulkan loader is not installed, not 
found, or failed to load.
```
I don't know if something should be patched before building itself.
But if I run: `LD_LIBRARY_PATH=$(guix build vulkan-loader)/lib vulkaninfo`, 
the program will be executed without any error.

If I wrap only with vulkan-loader's library path also, it works. But would it 
be a "right" way of wrapping a program.

Yes, you are right. I will change it.
