This is an educational task aimed at understanding how to link with static and dynamic libraries and use dlopen(3) at runtime.

libfoo — static library
libbar — dynamic library, linked
libbaz — dynamic library, loaded with dlopen
foobarbaz — executable that loads the 3 libs

$ mkdir build
$ cd build
$ cmake .. -DCMAKE_INSTALL_PREFIX=../prefix
$ make install
$ cd ../prefix/bin
$ LD_LIBRARY_PATH=. ./foobarbaz   # Prints 'FooBarBaz'
$ ldd ./foobarbaz   # Does not show libbaz.so
