Hi,
I am having problems in trying to use a dependency on a -l if the
directory the library is built in does not exist when the build starts.
(See below for simple example.)
I know how to work around the problem by depending on the file
explicately and linking it in with -L and -l on the command line,
but was hoping to use this nifty looking syntax. Seemed like it would
help in using more generalized rules.
