-Subject: [PATCH] Include <boost/lexical_cast.hpp> explicitly
-
-UHDSoapyDevice.cpp and SoapyUHDDevice.cpp use boost::lexical_cast but
-relied on it being pulled in transitively by another boost header.
-Recent Boost no longer does so, breaking the build with
-'lexical_cast is not a member of boost'. Include it directly.
