[Bug]: recoll's `recollindex` binary linking issue

[JCGoran]

Problem description

Recoll uses the recollindex binary (see for instance the online manpage) to perform the actual indexing of files on the filesystem; unfortunately, it seems that the linking in Termux is not working as intended, as when I run recollindex, I get the following error message:

CANNOT LINK EXECUTABLE "recollindex": library "librecoll-1.33.4.so" not found: needed by main executable

with an exit code 1.

What steps will reproduce the bug?

1. install the recoll package: apt install recoll
2. run recollindex

What is the expected behavior?

The recollindex binary should find the library at the proper path, which seems to be at /data/data/com.termux/files/usr/lib/recoll/librecoll-1.33.4.so. After some experimentation, running something like:

export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:$PREFIX/lib/recoll"

seems to do the trick, and recollindex can successfully index the files.
