Check whether the compiler supports a given link flag.
check_linker_flag(<lang> <flag> <var>)
Check that the link
<flag> is accepted by the
<lang> compiler without a diagnostic. Stores the result in an internal cache entry named
This command temporarily sets the
CMAKE_REQUIRED_LINK_OPTIONS variable and calls the
check_source_compiles() command from the
CheckSourceCompiles module. See that module’s documentation for a listing of variables that can otherwise modify the build.
A positive result from this check indicates only that the compiler did not issue a diagnostic message when given the link flag. Whether the flag has any effect or even a specific one is beyond the scope of this module.
