Bug description When building the helloworld example, linker reports that it cannot find -lhero-target although libhero-target.so exists and path given to the linker with -L flag is valid.

To Reproduce

  1. source scripts/hero-z-7045-env.sh
  2. cd hero-openmp-examples/helloworld
  3. make clean all
  4. Build fails

Dear @alessandrocapotondi,

I have found the solution to the problem be running the last step from the builder script, in other words running ./hero-z-7045-builder -i, even though another computer has already done this step and the driver is already running on the board. The problem arose from my misunderstanding that the install step of the builder script only cross-compiles the necessary drivers and programs for the board and copies them over ssh to the board.

In my opinion this is not that intuitive and could maybe be better that the builder script enables building the examples without having the board already plugged in and ready with the built linux on.

Hope this helps. Ask me for any further information that you need.
