.. versionadded:: 3.7 | |
Honor per-config flags in :command:`try_compile` source-file signature. | |
The source file signature of the :command:`try_compile` command uses the value | |
of the :variable:`CMAKE_<LANG>_FLAGS` variable in the test project so that the | |
test compilation works as it would in the main project. However, CMake 3.6 and | |
below do not also honor config-specific compiler flags such as those in the | |
:variable:`CMAKE_<LANG>_FLAGS_DEBUG` variable. CMake 3.7 and above prefer to | |
honor config-specific compiler flags too. This policy provides compatibility | |
for projects that do not expect config-specific compiler flags to be used. | |
The ``OLD`` behavior of this policy is to ignore config-specific flag | |
variables like :variable:`CMAKE_<LANG>_FLAGS_DEBUG` and only use CMake's | |
built-in defaults for the current compiler and platform. | |
The ``NEW`` behavior of this policy is to honor config-specific flag | |
variabldes like :variable:`CMAKE_<LANG>_FLAGS_DEBUG`. | |
This policy was introduced in CMake version 3.7. Unlike most policies, | |
CMake version |release| does *not* warn by default when this policy | |
is not set and simply uses ``OLD`` behavior. See documentation of the | |
:variable:`CMAKE_POLICY_WARNING_CMP0066 <CMAKE_POLICY_WARNING_CMP<NNNN>>` | |
variable to control the warning. | |
