please excuse my dumb question, but i recently need an SPI lib for an Attiny85 and found one here GitHub - JChristensen/tinySPI: Arduino hardware SPI library for ATtiny44/84, 45/85, 461/861, 2313/4313.
I put it into My Documents/Arduino/libraries and use is this way in my project: #include <tinySPI.h> which seems to work.
But then i wanted to use it in combination with another lib, which depends on SPI communication and uses #include <SPI.h> many times inside his own .h and .cpp files. It throws dozends of errors while compiling, claiming that there is already an exported symbol called SPI.
I hope there is a way to use some kind of preferred lib loading or to keep own versions just inside the project folder to be update safe.
