Draft cmake integration

[cristian-vijelie]

Currently, only the binaries in app-interact are built with cmake. To build, run

.../operating-systems/content$ mkdir build/ && cd build/
.../operating-systems/content/build$ cmake -S .. -B .
.../operating-systems/content/build$ make -j $(nproc)

All executables will be built in the build/ folder, following a structure similar to the source files locations.

For example, the executable generated from content/chapters/app-interact/lab/support/password-cracker/password-cracker-multiprocess.c will be located in content/build/chapters/app-interact/lab/support/password-cracker/

Closes #268
