I need to clarify this. cpprestsdk/2.10.13 uses the conan modular boost packages (boost_*/1.69.0@bincrafters/stable) and NOT as I thought boost/1.69.0@conan/stable.

I'll change the title in "Modular boost packages [boost_*/1.69.0@bincrafters/stable] uses ranlib from Xcode while cross compile to Android" later.
