# INFORMATION / HELP

|
|
# The following arguments control the behaviour of this toolchain:
|
|
#
|
|
# PLATFORM: (default "OS")
|
|
# OS = Build for iPhoneOS.
|
|
# OS64 = Build for arm64 iphoneOS.
|
|
# OS64COMBINED = Build for arm64 x86_64 iphoneOS. Combined into FAT STATIC lib (supported on 3.14+ of CMakewith "-G Xcode" argument ONLY)
|
|
# SIMULATOR = Build for x86 i386 iphoneOS Simulator.
|
|
# SIMULATOR64 = Build for x86_64 iphoneOS Simulator.
|
|
# TVOS = Build for arm64 tvOS.
|
|
# TVOSCOMBINED = Build for arm64 x86_64 tvOS. Combined into FAT STATIC lib (supported on 3.14+ of CMake with "-G Xcode" argument ONLY)
|
|
# SIMULATOR_TVOS = Build for x86_64 tvOS Simulator.
|
|
# WATCHOS = Build for armv7k arm64_32 for watchOS.
|
|
# WATCHOSCOMBINED = Build for armv7k arm64_32 x86_64 watchOS. Combined into FAT STATIC lib (supported on 3.14+ of CMake with "-G Xcode" argument ONLY)
|
|
# SIMULATOR_WATCHOS = Build for x86_64 for watchOS Simulator.
|
|
#
|
|
# CMAKE_OSX_SYSROOT: Path to the SDK to use. By default this is
|
|
# automatically determined from PLATFORM and xcodebuild, but
|
|
# can also be manually specified (although this should not be required).
|
|
#
|
|
# CMAKE_DEVELOPER_ROOT: Path to the Developer directory for the platform
|
|
# being compiled for. By default this is automatically determined from
|
|
# CMAKE_OSX_SYSROOT, but can also be manually specified (although this should
|
|
# not be required).
|
|
#
|
|
# DEPLOYMENT_TARGET: Minimum SDK version to target. Default 2.0 on watchOS and 9.0 on tvOS+iOS
|
|
#
|
|
# ENABLE_BITCODE: (1|0) Enables or disables bitcode support. Default 1 (true)
|
|
#
|
|
# ENABLE_ARC: (1|0) Enables or disables ARC support. Default 1 (true, ARC enabled by default)
|
|
#
|
|
# ENABLE_VISIBILITY: (1|0) Enables or disables symbol visibility support. Default 0 (false, visibility hidden by default)
|
|
#
|
|
# ENABLE_STRICT_TRY_COMPILE: (1|0) Enables or disables strict try_compile() on all Check* directives (will run linker
|
|
# to actually check if linking is possible). Default 0 (false, will set CMAKE_TRY_COMPILE_TARGET_TYPE to STATIC_LIBRARY)
|
|
#
|
|
# ARCHS: (armv7 armv7s armv7k arm64 arm64_32 i386 x86_64) If specified, will override the default architectures for the given PLATFORM
|
|
# OS = armv7 armv7s arm64 (if applicable)
|
|
# OS64 = arm64 (if applicable)
|
|
# SIMULATOR = i386
|
|
# SIMULATOR64 = x86_64
|
|
# TVOS = arm64
|
|
# SIMULATOR_TVOS = x86_64 (i386 has since long been deprecated)
|
|
# WATCHOS = armv7k arm64_32 (if applicable)
|
|
# SIMULATOR_WATCHOS = x86_64 (i386 has since long been deprecated)
|
|
#
|
|
# This toolchain defines the following variables for use externally:
|
|
#
|
|
# XCODE_VERSION: Version number (not including Build version) of Xcode detected.
|
|
# SDK_VERSION: Version of SDK being used.
|
|
# CMAKE_OSX_ARCHITECTURES: Architectures being compiled for (generated from PLATFORM).
|
|
#
|
|
# This toolchain defines the following macros for use externally:
|
|
#
|
|
# set_xcode_property (TARGET XCODE_PROPERTY XCODE_VALUE XCODE_VARIANT)
|
|
# A convenience macro for setting xcode specific properties on targets.
|
|
# Available variants are: All, Release, RelWithDebInfo, Debug, MinSizeRel
|
|
# example: set_xcode_property (myioslib IPHONEOS_DEPLOYMENT_TARGET "3.1" "all").
|
|
#
|
|
# find_host_package (PROGRAM ARGS)
|
|
# A macro used to find executable programs on the host system, not within the
|
|
# environment. Thanks to the android-cmake project for providing the
|
|
# command.
