[Coin-discuss] AC_COIN_HAS_USER_LIBRARY

[Andreas Waechter]

Hi Lee

Actually, the idea is to specify -lpthread in the configure command line 
argument for the cplex library, e.g.

configure [...]  --with-cplex-lib='-L/usr/local/wherever -lcplex -lpthread'

The documentation is probably not very clear, those user libraries 
--with-xxx-lib flags are meant to be given ALL link flags for that 
particular library, including additional libraries.

Does that fix your problem, so that no modification of the m4 macro is 
necessary anymore?
