# CMAKE_SYSROOT

Path to pass to the compiler in the `--sysroot` flag.

The `CMAKE_SYSROOT` content is passed to the compiler in the `--sysroot` flag, if supported. The path is also stripped from the RPATH/RUNPATH if necessary on installation. The `CMAKE_SYSROOT` is also used to prefix paths searched by the `find_*` commands.

This variable may only be set in a toolchain file specified by the `CMAKE_TOOLCHAIN_FILE` variable.
