In MIP_HOME/main/examples there are the source code of examples executables that are made to show the usage of resources or algorithms. These are not built by default.
To build a set of examples with source named example1.cpp and example2.cpp, go in MIP_HOME and execute:
$ cmake -DMIP_EXAMPLES="example1 example2" .
$ make
You could need to erase the chache file before:
$ cd MIP_HOME/build/
$ rm CMakeCache.txt
