Thanks. Seeing a list of packages that use BinDeps helps. In
retrospect, I could have put BinDeps in the subject line so this
thread could be found more easily.
The two downloaded packages use Autotools. BinDeps works great once I
got the incantation right.
So, I have been trying to follow the BinDeps test code in faking that
the wrapper code (one file) uses Autotools by supplying a
configure script, so that ./configure, make , make install works. I was
hoping to essentially copy the two or three lines per
dep that are in my current build.jl.
Anyway, this is probably enough help to get me quite a bit further.

BinDeps is pretty flexible.I'm guessing you have seen a BinDeps invocation that is based off of the
Autotools step? (Here's an example for Nettle.jl) That does a lot of
things for you, and doesn't really show off the flexibility that well.

PACKAGE_ROOT/deps/src folder, then you can write up a set of simple
build steps to cd into that directory, (Notice BinDeps.srcdir(dep) will
give you paths like you were asking above) you can run `make`, and then
install the binary anywhere you want.

packages ? I am using BinDeps to download two C++ libraries. After a lot
of blind trial and error I have a build.jl that does what I need. But, I
need to write a c wrapper for the C++ libraries. One idea is to have
BinDeps handle the build, if I can fool it into thinking it is an
external library. But, I don't know how to do that. BinDeps seems to
want to download something. I find it rather opaque. Otherwise I need to
find a way to write most of what BinDeps does by hand for my C code:
find paths to top level of the package and various sub dirs; do change
dirs, making, copying, linking at run time, etc. I spent quite a bit of
time searching julia-user, and -dev, grepping and finding in package
trees, reading docs and source code, etc. no luck. Thanks.
