I have enabled "IncludeExperimentalModels" in cmake, and the names of these models, i.e. IsotropicDiff2, RiemannLifted2_Periodic, and DubinsExt2, are correctly displayed in cmake as "ExperimentalModelNames". But after compiling, only the executables of standard models are built.
I am using gcc 5.4.0 on Ubuntu 16.04.
