For Makefile generators this +produces an error at build time because the dependency on the full +path cannot be found. For VS IDE and Xcode generators this used to +work by accident because CMake would always split off the library +directory and ask the linker to search for the library by name +(-lsomelib or somelib.lib). Despite the failure with Makefiles, some +projects have code like this and build only with VS and/or Xcode. +This version of CMake prefers to pass the full path directly to the +native build tool, which will fail in this case because it does not +name a valid library file. + +This policy determines what to do with full paths that do not appear +to name a valid library file. The OLD behavior for this policy is to +split the library name from the path and ask the linker to search for +it. The NEW behavior for this policy is to trust the given path and +pass it directly to the native build tool unchanged. + +This policy was introduced in CMake version 2.6.1. CMake version +|release| warns when the policy is not set and uses OLD behavior. Use +the cmake_policy command to set it to OLD or NEW explicitly. |
