We don't normally try to generate the XCode project files, but it should just be a matter of changing the

-G

option from

Ninja

to the XCode one. I also suggest passing

-DADD_HEADERS_AS_SOURCES=ON

when configuring, and if you haven't built yet, build the

prepare_for_ide

target with

cmake --build . --target prepare_for_ide

. Then when opening the project XCode should be able to find all the headers.
