Feature request: cmake alias library

[pfeatherstone]

Feature request

It would be great if you could do this in cmake:

add_executable(myexe ...)
target_link_libraries(myexe PRIVATE UHD::UHD) # For dynamic linking
target_link_libraries(myexe PRIVATE UHD::UHD_STATIC) # For static linking

Then we wouldn't have to worry about all of the following:

• ${Boost_INCLUDE_DIRS}
• ${UHD_INCLUDE_DIRS}
• UHD_USE_STATIC_LIBS
• ${Boost_LIBRARY_DIRS}
• ${UHD_LIBRARIES}
• ${UHD_STATIC_LIB_LINK_FLAG}
• ${UHD_STATIC_LIB_DEPS}
