Add options to specify the linker tool
Offer the capability, through variable CMAKE_LINKER_TYPE
, as well as the target property LINKER_TYPE
to specify which linker must be used.
The implementation of this capability is specified by variables specific to the language and linker type: CMAKE_<LANG>_USING_LINKER_<TYPE>
. Some definitions are provided as part of CMake
.
For example, to select the LLVM
linker rather than the standard one, the type LLD
should be specified through the variable CMAKE_LINKER_TYPE
. And, on Apple
, Linux
and some environments on Windows
, the variable CMAKE_<LANG>_USING_LINKER_LLD
has value -fuse-ld=lld
. And for Windows
environments based on MSVC
, where the linker is used directly, the tool lld-link.exe
will be used rather than link.exe
.
