# Manu: I hardcoded the paths to the library libpololu-tic-1
# and to the header file tic.hpp,
# rather than using the cmake find_path and find_library functions.
# I found the paths by typing in terminal:
# $(pkg-config libpololu-tic-1 --cflags --libs)
# which outputed:
# -I/usr/local/include/libpololu-tic-1 -L/usr/local/lib -lpololu-tic-1
# I was inspired by the code example in the Pololu Tic documentation,
# which was compiled by typing:
# g++ code.cpp $(pkg-config libpololu-tic-1 --cflags --libs)
