Prior to this change when trying to cross compile:

$ cat ../_h_env/lib/pkgconfig/blosc2.pc 
prefix=/home/conda/feedstock_root/build_artifacts/debug_1680560464317/_h_env
exec_prefix=${prefix}
libdir=${exec_prefix}//home/conda/feedstock_root/build_artifacts/debug_1680560464317/_h_env/lib

This causes pkg-config to output incorrect path, and ultimately the application fails to link.

$ pkg-config --libs blosc2
-L/home/conda/feedstock_root/build_artifacts/debug_1680560464317/_h_env//home/conda/feedstock_root/build_artifacts/debug_1680560464317/_h_env/lib -lblosc2

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

Thank you for the investigation!

Good fix.

looking at the logs, it seems we can just remove this entirely:
