[issue9998] ctypes find_library should search LD_LIBRARY_PATH on linux

[Martin Panter]

Martin Panter added the comment:

I tend to agree with the comment at <https://bugs.python.org/issue2936#msg67505>. Find_library() is documented as emulating a build-time linker, not run-time. Build-time linking ignores LD_LIBRARY_PATH.

Maybe it would make more sense to pass in an optional list of -L directories to search, but it really depends on what the use cases are.

Pau: What is wrong with the more direct CDLL("libspatialindex_c.so") proposal that bypasses find_library()?
