CMAKE_<LANG>_LINK_FLAGS

Добавлено в версии 4.3.

Language-wide flags for language <LANG> used when linking for all configurations. These flags will be passed to all invocations of the compiler which drive linking.

The flags in this variable will obey the following behavior with respect to ordering of flags from other variables.

• They will be passed after those added by CMAKE_<LANG>_FLAGS and CMAKE_<LANG>_FLAGS_<CONFIG>.

• They will be passed after those added by CMAKE_EXE_LINKER_FLAGS, CMAKE_EXE_LINKER_FLAGS_<CONFIG>, CMAKE_SHARED_LINKER_FLAGS, CMAKE_SHARED_LINKER_FLAGS_<CONFIG>, CMAKE_MODULE_LINKER_FLAGS, and CMAKE_MODULE_LINKER_FLAGS_<CONFIG> depending on the given target type.

• They will be passed before those added by CMAKE_<LANG>_LINK_FLAGS_<CONFIG>.

• They will be passed before those added by commands such as add_link_options() and target_link_options().

Use of this variable is enabled when policy CMP0210 is NEW.

Handling Compiler Driver Differences

Добавлено в версии 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".

Примечание

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.
