Missing library paths for custom Boost builds

Builds with custom Boost need -L/path/to/Boost

• Are you running the latest graph-tool version?
• Do you observe the problem with the current git version?
• Are you using Macports or Homebrew? If yes, please submit an issue there instead: https://github.com/Homebrew/brew/issues and https://trac.macports.org/newticket
• Did you compile graph-tool manually?

Yes

• If you answered yes above, did you use the exact same compiler to build graph-tool, boost-python and Python?

Yes (Python built by distribution but used same compiler version)

Compilation fails during linking of libgraph_tool_centrality.la. -lboost_coroutine -lboost_context were supplied to the linker but not the critical -L/path/to/boost given to configure's --with-boost argument. The following patch fixes the problem for me:

diff --git a/configure.ac b/configure.ac

but I am not sure this is the right thing to do. config.logconfigure_output

• A minimal and self-contained example that shows the problem.
• Your operating system.

Ubuntu 18.10

• The Python version you are using.

3.7.1

• If you compiled graph-tool manually: Your compiler version, as well as the version of Boost being used.

gcc 8.2.0 and Boost 1.68.0

• If you are reporting a compilation error, please provide the entire ./configure output, as well as the entire contents of the config.log file and the entire compilation output.
