## Interprocedural optimization
[This](https://cmake.org/cmake/help/latest/variable/CMAKE_INTERPROCEDURAL_OPTIMIZATION.html) is available on very recent versions of CMake. You can turn this on with `CMAKE_INTERPROCEDURAL_OPTIMIZATION` (CMake 3.9+ only) or the `INTERPROCEDURAL_OPTIMIZATION` property on targets. Support for GCC and Clang was added in CMake 3.8. In `cmake_minimum_required(VERSION 3.9)`, setting this to `ON` on a target is an error if the compiler doesn't support it. You can use [`check_ipo_supported()`](https://cmake.org/cmake/help/latest/module/CheckIPOSupported.html), from the built-in `CheckIPOSupported` module, to see if support is available before hand. An example of 3.9 style usage:
«prop:tgt:INTERPROCEDURAL_OPTIMIZATION», best known as *link time optimization* and the `-flto` flag, is available on very recent versions of CMake. You can turn this on with «variable:CMAKE_INTERPROCEDURAL_OPTIMIZATION» (CMake 3.9+ only) or the «prop:tgt:INTERPROCEDURAL_OPTIMIZATION» property on targets. Support for GCC and Clang was added in CMake 3.8. If you set `cmake_minimum_required(VERSION 3.9)` or better (see «policy:CMP0069»), setting this to `ON` on a target is an error if the compiler doesn't support it. You can use check_ipo_supported(), from the built-in «module:CheckIPOSupported» module, to see if support is available before hand. An example of 3.9 style usage:
