Libtool discovers any additional required libraries by reading 
installed ".la" text files.  It is quite possible for a ".la" to 
include an incomplete dependency listing and still work for shared 
library builds since Linux automatically adds more libraries at link 
and run time based on dependencies coded into the various .so files. 
However, static builds need to be fully-specified since static 
libraries don't store any implicit dependencies, and they need to 
satisfy all static linkage requirements at link time.

Many Linux distributions intentionally omit the .la files.
