[bug] BazelDeps fails to generate with libpng due to cpp_info.location

[valgur]

Describe the bug

Conan 2.10.2
Ubuntu 24.04

ERROR: Error in generator 'BazelDeps': libpng/1.6.44: Cannot obtain 'location' for library 'png' in ['/home/martin/.conan2/p/b/libpn667f314ae558c/p/lib']. You can specify 'cpp_info.location' directly or report in github.com/conan-io/conan/issues if you think it should have been deduced correctly.

The only thing of note about the libpng recipe that I can see is that it's missing package_type, but adding it does not fix the issue.

How to reproduce it

conan install . this conanfile.txt

[requires]
libpng/[>=1.6 <2]

[generators]
BazelDeps

[valgur]

The content of package_folder for libpng is:

├── conaninfo.txt
├── conanmanifest.txt
├── include
│   ├── libpng16
│   │   ├── pngconf.h
│   │   ├── png.h
│   │   └── pnglibconf.h
│   ├── pngconf.h
│   ├── png.h
│   └── pnglibconf.h
├── lib
│   ├── cmake
│   │   └── PNG
│   ├── libpng16.a
│   └── libpng.a -> libpng16.a
└── licenses
    └── LICENSE

My guess is that it's ignoring the libpng.a/libpng.so symlink for some reason.

Hi @valgur

Thanks a lot for reporting this 😁
Indeed, it was a bug, but this PR #17421 already solves it.
It'll be released in the next Conan 2.11.0 👏

Closing the issue as solved, but do not hesitate to reopen if there is still any other problem.

Indeed, I can confirm that it's fixed in develop2. Thanks!
