@subsection gsg_universal Compiling a universal binary on macOS
With Xcode 12.2 and later you can compile libxlsxwriter as a "universal
binary" for both Apple silicon and Intel-based Macs, i.e., arm64 and x86_64.
You can compile a universal binary with standard make as follows:
$ make universal_binary
# Which gives:
$ lipo -archs lib/libxlsxwriter.a
x86_64 arm64
$ lipo -archs lib/libxlsxwriter.dylib
x86_64 arm64
Or with Cmake (see also @ref gsg_cmake):
cd cmake
cmake -DCMAKE_OSX_ARCHITECTURES="x86_64;arm64" ..
make

On macOS you can also use [brew/homebrew](https://brew.sh):
