# CMAKE_EXE_LINKER_FLAGS

Linker flags to be used to create executables.

These flags will be used by the linker when creating an executable.

## Handling Compiler Driver Differences

Added in version 4.0.

To pass options to the linker tool, each compiler driver has its own syntax. The `LINKER:` prefix and `,` separator can be used to specify, in a portable way, options to pass to the linker tool. `LINKER:` is replaced by the appropriate driver option and `,` by the appropriate driver separator. The driver prefix and driver separator are given by the values of the `CMAKE_<LANG>_LINKER_WRAPPER_FLAG` and `CMAKE_<LANG>_LINKER_WRAPPER_FLAG_SEP` variables.

For example, `"LINKER:-z,defs"` becomes `-Xlinker -z -Xlinker defs` for `Clang` and `-Wl,-z,defs` for `GNU GCC`.

The `LINKER:` prefix supports, as an alternative syntax, specification of arguments using the `SHELL:` prefix and space as separator. The previous example then becomes `"LINKER:SHELL:-z defs"`.

Note

Specifying the `SHELL:` prefix anywhere other than at the beginning of the `LINKER:` prefix is not supported.

This support implies to parse and re-quote the content of the variable. See policy `CMP0181`.
