CMake +versions 2.4 and below assumed that only trivial values would be given +for macros in add_definitions calls. It did not attempt to escape +non-trivial values such as string literals in generated build rules. +CMake versions 2.6 and above support escaping of most values, but +cannot assume the user has not added escapes already in an attempt to +work around limitations in earlier versions. + +The OLD behavior for this policy is to place definition values given +to add_definitions directly in the generated build rules without +attempting to escape anything. The NEW behavior for this policy is to +generate correct escapes for all native build tools automatically. +See documentation of the COMPILE_DEFINITIONS target property for +limitations of the escaping implementation. + +This policy was introduced in CMake version 2.6.0. 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. |
