I just did a test and it looks like it works.
make sure the pins are free, always making unexport_gpio exit the program.
launch the program as superuser with: sudo ./bin/example-simple-led
you can check whether resources are released by controlling the folder:
ls /sys/class/gpio/

Thank you Kashim,
You're right, it works with sudo ./bin/example-simple-led
I've also found this tricks to authorize permissions for pi

usually I do not recommend to change the permissions on the folder sys, for his ties to kernel mode.
but it can be done easily if you know your system.
even by simply using:
chmod 777 namedeviceorfile
or
chown pi: pi namedeviceorfile
