CMAKE_<LANG>_USING_LINKER_<TYPE>ΒΆ
New in version 3.29.
This variable defines how to specify the <TYPE> linker for the link step,
as controlled by the CMAKE_LINKER_TYPE variable or the
LINKER_TYPE target property. Depending on the value of the
CMAKE_<LANG>_USING_LINKER_MODE variable,
CMAKE_<LANG>_USING_LINKER_<TYPE> can hold compiler flags for the link step,
or flags to be given directly to the linker tool.
Note
The specified linker tool is generally expected to be accessible through
the PATH environment variable.
For example, the LLD linker for GNU compilers is defined like so:
set(CMAKE_C_USING_LINKER_LLD "-fuse-ld=lld")
On the Windows platform with Clang compilers simulating MSVC:
set(CMAKE_C_USING_LINKER_LLD "-fuse-ld=lld-link")
And for the MSVC compiler, the linker is invoked directly, not via the
compiler frontend:
set(CMAKE_C_USING_LINKER_LLD "/path/to/lld-link.exe")
set(CMAKE_C_USING_LINKER_MODE TOOL)
A custom linker type can also be defined, usually in a toolchain file:
set(CMAKE_LINKER_TYPE lld_launcher)
set(CMAKE_C_USING_LINKER_lld_launcher "-fuse-ld=/path/to/lld-launcher.sh")
set(CMAKE_C_USING_LINKER_MODE FLAG)
