| |
| |
| # Options |
| # ------- |
| # |
| # IOS_PLATFORM = OS | SIMULATOR |
| # |
| # This decides whether SDKS are selected from the `iPhoneOS.platform' or |
| # `iPhoneSimulator.platform' folders. |
| # |
| # OS - the default, used to build for iPhone and iPad physical devices, |
| # which have an ARM architecture. |
| # SIMULATOR - used to build for the Simulator platforms, which have an |
| # x86 architecture. |
| # |
| # CMAKE_IOS_DEVELOPER_ROOT = /path/to/platform/Developer folder |
| # |
| # By default, this location is automatically chosen based on the |
| # IOS_PLATFORM value above. If you manually set this variable, it |
| # overrides the default location and forces the use of a particular |
| # Developer Platform. |
| # |
| # CMAKE_IOS_SDK_ROOT = /path/to/platform/Developer/SDKs/SDK folder |
| # |
| # By default, this location is automatically chosen based on the |
| # CMAKE_IOS_DEVELOPER_ROOT value. In this case it is always the most |
| # up-to-date SDK found in the CMAKE_IOS_DEVELOPER_ROOT path. If you |
| # manually set this variable, it forces the use of a specific SDK |
| # version. |
| # |
