| CMAKE_SYSROOT_LINK | |
| ------------------ | |
| Path to pass to the compiler in the ``--sysroot`` flag when linking. This is | |
| the same as :variable:`CMAKE_SYSROOT` but is used only for linking and not | |
| compiling sources. | |
| This variable may only be set in a toolchain file specified by | |
| the :variable:`CMAKE_TOOLCHAIN_FILE` variable. |
