macOS support builds but doesn't work

[daminetreg]

By merging #1 we made it compile for macOS, thanks to @linkineo, but it doesn't work for the moment, due to some paths issues.

It can be reproduced easily by cloning https://github.com/header-only/example-dependency and checking out the list-your-deps tag, then running inglued seal as presented below :

Damiens-MacBook-Pro:inglued daminetreg$ cd example/example-dependency/
Damiens-MacBook-Pro:example-dependency daminetreg$ git checkout list-your-deps
Damiens-MacBook-Pro:example-dependency daminetreg$ ../../build/inglued seal
Fetching and glueing in your git repository direct dependencies:

It might be due to the passing of arguments to the bp::child, but might as well be something else. Have to investigate.

Solved in #3. Test is now passing with the example above.

Indeed checked it's solved in #3 .
