locate() is greedy when matching library name

[ludvigak]

When called from write_deps_file(), locate() will happily match any library that begins with the same string as the library we are looking for: https://github.com/JuliaPackaging/BinaryProvider.jl/blob/cb403e6e19c5ec130b47cf3d85d8e9530adabd14/src/Products.jl#L158

In my case I was trying to use the library libgsl, which existed in the same folder as the library libgslcblas:

Info: Found a valid dl path libgslcblas.so while looking for libgsl
Info: /home/ludvigak/.julia/dev/GSL/deps/usr/lib/libgslcblas.so matches our search criteria of libgsl

I could fix this by changing LibraryProduct(prefix, ["libgsl"], :libgsl) to LibraryProduct(prefix, ["libgsl."], :libgsl) in the build script, but that was not obvious from the start.

This greedy matching could be considered a feature or a bug, depending on how you want things to work.

This should be considered a bug. We’ll fix it ASAP
