This allows multiple source files in a +target to share the same name if they lie in different directories +without rebuilding when one is added or removed. However, it can +produce long full paths in a few cases, so CMake shortens the path +using a hashing scheme when the full path to an object file exceeds a +limit. CMake has a built-in limit for each platform that is +sufficient for common tools, but some native tools may have a lower +limit. This variable may be set to specify the limit explicitly. The +value must be an integer no less than 128. |
