CMAKE_SHARED_LINKER_FLAGS

Linker flags to be used to create shared libraries.

These flags will be used by the linker when creating a shared library.

Handling Compiler Driver Differences

Added in version 3.32.

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.
