That link looks fine to me. You might want to verify that the CMAKE_DL_LIBS
variable actually contains what it should on your system (or a least
contains what it should right before using it).
You could explicitly add the "-dl" to that link statement and see if that
works. That's what that variable should contain anyways on Linux boxes.

Thanks, Caleb. Are you saying that I need to add "-ldl" link lib in
addition to ${CMAKE_DL_LIBS} ?
My CMake file is here:
https://github.com/GrokImageCompression/opendcp/blob/master/cli/CMakeLists.txt
and the lines for the exe that is not linking are found here:
TARGET_LINK_LIBRARIES(opendcp_j2k ${CMAKE_DL_LIBS} ${OPENDCP_LIB} )
This is an open source proj, by the way. I can send you a few short lines
about how to build on Ubuntu, if you are interested.
Thanks very much for your help.
