I resolved this by adding set(CMAKE_CXX_STANDARD_LIBRARIES -ldl) to my cmakelists, or -Wl,--no-as-needed -ldl to my g++ options. Maybe this should be added to the wiki?

If you enter the distribution directory cppad-20180000.0 and execute the command
bin/run_cmake.sh
and then execute
cd build
make check_example_general
does the HesLagrangian example report OK ?

Did the commands above work before you changed any of the CppAD CMakeLists.txt files ?
If not, do you have a suggested change to get it to work.
If yes, then the following command would show the flags used to compile and link the example
bin/run_cmake.sh --verbose
cd build
make clean
make check_example_general
My mistake: I thought this was a CppAD bug report, instead of a CppADCodeGen bug report.

The above worked before I changed any CppAD CMakeLists.txt files, yes. The issue I had was in using CppADCodeGen in my own project. I suggested the CMakeLists.txt flag that I needed to include in my project.
As for those flags, would you like me to report what make does here when I run that?

To know how to build an example I would suggest to look at
https://github.com/joaoleal/CppADCodeGen/blob/master/example/CMakeLists.txt
Regarding the Lagrangian, the key section is:
############################################################################
# lagrangian
############################################################################
ADD_EXECUTABLE(lagrangian lagrangian.cpp)
SET(EXAMPLES_COMMAND "${EXAMPLES_COMMAND} COMMAND lagrangian")
TARGET_LINK_LIBRARIES(lagrangian ${DL_LIBRARIES})
ADD_CUSTOM_TARGET(example_lagrangian
COMMAND lagrangian)from cppadcodegen.

Thank you for the reply. I somehow missed this CMakeLists.txt file. I believe it was the ${DL_LIBRARIES} that I forgot.
