Thank you all for your tips/advice.
From our experience IDE generators (eg. Visual Studio, Xcode) is
much slower than Make or Ninja. I will attach benchmarks later.
Unfortunately I'm unable to build Universal libraries for x86 and arm
architectures by using Makefile.
This feature will work only for Xcode. For Makefile generator
variable/property IOS_INSTALL_COMBINED is ignored. Xcode and Makefile
differs in internals. Xcode can hold in build directory all variants of
library like Release/Debug + Simulator/Device:
Debug-iphoneos/libfoo.a # xcodebuild -sdk iphoneos -config Debug
Debug-iphonesimulator/libfoo.a # xcodebuild -sdk iphonesimulator -config
Debug
Release-iphoneos/libfoo.a # xcodebuild -sdk iphoneos -config Release
Release-iphonesimulator/libfoo.a # xcodebuild -sdk iphonesimulator
-config Release
Makefile holds only one variant so building both Simulator/Device in one
project is tricky. You can build/install several libraries by Makefile
and combine them with lipo using some external script.
See attached logs.
It seems that two different SDK's (iPhoneOS and iPhoneSimulator) needs
to be used in that case.
Do you know how it could be fixed?
Maybe I should add "CMAKE_OSX_SYSROOT "iphoneos" support for other
generators?
What do you think about that idea?
Thanks in advance

PS
I'm attaching the script which I'm using for testing purposes.
To reproduce it just run command (from command line):
cd builddir && cmake .. && cmake --build .

Thanks Ruslan.
I would like to create instruction which is universal for all
generators.
I think it's not possible. E.g. IOS_INSTALL_COMBINED will work only
for Xcode.
Currently we would like to support both Make/Ninja and Xcode generators,
...
because Make is much faster than Xcode generator, and we are using it
in our CI system.
Do you mean generate step or build? I've used to compile quite big
projects like OpenCV with Xcode and according to the `top` it uses all
my cores with clang++ at 100% CPU time.
Can you show any benchmarks? Also note that Xcode can add some
additional stuff, like dSYM:
https://github.com/headupinclouds/gatherer/pull/69
Make is also common for other architectures (Linux, QNX, Android etc.)
Unfortunately
set(CMAKE_OSX_SYSROOT "iphoneos")
is not working for me.
It displays error:
/Users/warsaw/Perforce/cmake-dev/cmake-build/bin/cmake .. &&
/Users/warsaw/Perforce/cmake-dev/cmake-build/bin/cmake --build .

clang: warning: no such sysroot directory: 'iphoneos'
...
Do you have some tip for that?
Yes, this hint was for Xcode generator.
After removing "-isysroot ${CMAKE_OSX_SYSROOT}" everything works
perfectly. Thanks
Unfortunately CMAKE_XCODE_ATTRIBUTE_IPHONEOS_DEPLOYMENT_TARGET is not
working with Make.
Is it possible to introduce CMAKE_IOS_DEPLOYMENT_TARGET, as we already
have CMAKE_OSX_DEPLOYMENT_TARGET?
Since OSX_ARCHITECTURES controls iOS architectures too I think request
should sounds like "Extend OSX_DEPLOYMENT_TARGET property for iOS
platform".
I have attached my example script which I'm using.
Could you please modify it to be better (and still support other
generators)?
I don't know how to use iOS target with Makefile generator.
Some notes about project you've sent:
* You need to add instructions to codesign your bundle
* Instead of hardcoding `set(CMAKE_OSX_SYSROOT
"/Applications/Xcode.app/.../iPhoneSimulator.sdk")` you can run
`xcode-select -print-path` to detect location of default Xcode version
* Should be `set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS}
-mios-version-min=8.0")` instead of `set(CMAKE_CXX_FLAGS
"-mios-version-min=8.0")` otherwise some flags may be lost

Hi
To enable iOS build, I'm using following settings in CMakeLists.txt:
set(APPLE_PLATFORM "iphonesimulator")
I think this
