| This is a cobbled-together CMake toolchain file for using "hermetic Xcode", |
| rather than the system-installed one. It is not used by default. It is meant to |
| be used on automated builder bots to avoid depending on system dependencies, but |
| can also be used locally. |
| |
| Use this by passing `-DCMAKE_TOOLCHAIN_FILE=path/to/HermeticXcode.cmake` to |
| `cmake`. |
| |
| Notes: |
| |
| - Not all of the variables set in the script are probably actually used |
| (and thus could break later on if they become used), but are included in an |
| attempt at completeness. |
| - `ranlib` is a link to `libtool` because those are the same binary with |
| different names. (It needs to be a symlink because it chooses its behavior |
| based on its filename.) |
| - It doesn't currently try to set up other things as hermetic, in particular |
| Python. |
