Ok.

What other way could I do it?

- There's no official definition of what should be found in LDFLAGS,
   but most of the software that use LDFLAGS (in particular autotools)
   expect you to put non-standard link directories in there.

- Isn't it the most standard way (in unix) to tell a build system to  
look
   for libraries in non-standard places?
