The MESSAGE directive shows it should be ok - added to
lib/CMakeLists.txt, after the first target_link_libraries(), the line
"MESSAGE(STATUS "DEBUG GR LIBS: ${GNURADIO_ALL_LIBRARIES}")".
The output:
/

/-- DEBUG GR LIBS:
/home/user/gr/lib/libgnuradio-runtime.so;/home/user/gr/lib/libgnuradio-pmt.so;/usr/lib/liblog4cpp.so;/home/user/gr/lib/libgnuradio-filter.so;/home/user/gr/lib/libgnuradio-fft.so;/home/user/gr/lib/libgnuradio-uhd.so/

I moved away all cmake/ files and then put them back one-by-one until
the build succeeded, which meant I ended up removing:
D cmake/Modules/CMakeParseArgumentsCopy.cmake
D cmake/Modules/FindGnuradioRuntime.cmake
D cmake/Modules/GrMiscUtils.cmake
D cmake/Modules/GrPython.cmake
D cmake/Modules/GrSwig.cmake
D cmake/Modules/GrTest.cmake
D cmake/Modules/UseSWIG.cmake
but still no luck (the undefined symbol error still exists).
It might be worth to mention, the version I use is 3.7.11.1.

add a "message ()" directive that prints the GNURADIO_ALL_LIBRARIES
that is actually used in your lib/CMakeLists.txt. If that is wrong:
Move your OOT's cmake/Modules/* out of the way – I do not endorse the
fact that we're distributing copies of all the GNU Radio CMake scripts
with our OOT template, as these might outdate locally.
I must admit I don't have an OOT where I test gr-uhd linkage myself.
Best regards,
