rem For using LLVM's libc++
rem Add -I$LIBCXX_INCLUDE to CFLAGS
rem Add -stdlib=libc++ -nostdinc++ -I$LIBCXX_INCLUDE to CXX FLAGS
rem Add -stdlib=libc++ -L$LIBCXX_LIB -lc++ -lc++abi -Wl,-rpath,$LIBCXX_LIB to LDFLAGS
rem Currently on MacOS this doesn't work, some errors with libc++ dylibs crashing app.

rem Build the project (uncomment if needed)
