On Mac, I kept getting error "Could not determine JNI include directories" when trying to do the custom setup.

The following fixed it for me:

I think the issue is on line 74 of CMakeLists.txt:

if(OS_NAME MATCHES "^Linux" OR OS_NAME STREQUAL "Mac")

"Mac" should be "Darwin".

I also tested with message(STATUS "OS_NAME detected as: ${OS_NAME}") and it prints Darwin.

I am on a 2020 Intel Mac.

Please let me know if anyone has encountered this error, and if it this a correct fix. Thank you!
