HTSlib installed but not found?

[vymao]

I have tried running ./build.sh with HTSlib as a loaded module (on a cluster) and built from source; however, both times I get the same message:

Would you know how to fix this?

Can you paste the contents of the htslib modulefile? I suspect it's not setting the LD_LIBRARY_PATH or LIBRARY_PATH variables correctly, or something like that. I'm testing it on my local machine with htslib version 1.10.2 and the configure script finds it just fine.
