I wonder how gnuradio got configured with uhd support? Thats actually
the one file the FindUHD.cmake looks for to confirm the header location:

FIND_PATH(
    UHD_INCLUDE_DIRS
    NAMES uhd/config.hpp
    HINTS $ENV{UHD_DIR}/include
        ${PC_UHD_INCLUDEDIR}
    PATHS /usr/local/include
          /usr/include
)

Thats just the first header it encounters. Theres probably some
installation issue. Can you post the ls <install prefix>/include/uhd/*
