L1VM - macOS build

I did a GitHub actions build on macOS 11. I got a few error messages:

Where is “features.h” defined in macOS 11? I did not have this error before! And “libl1vmmpfr.so” fails to build too!

Here is the log of the test programs tried to run. Both failed to load the “.so” libraries:

Did the search paths for “.so” libraries change? I have no clue yet! I did work some builds before! Can someone help me to fix this?

UPDATE:
I did add the following line to the macOS build script: 

cp /usr/local/include/c++/11/parallel/features.h /usr/local/include

I had to uncomment the search for “features.h” to search for it! Now the fann library demo works. And the SDL library check runs too, but without opening a screen. So it can’t be opened in the macOS build environmnet.
