Ignore CMAKE_SHARED_LIBRARY_<Lang>_FLAGS variable. | |
CMake 2.8.8 and lower compiled sources in SHARED and MODULE libraries | |
using the value of the undocumented CMAKE_SHARED_LIBRARY_<Lang>_FLAGS | |
platform variable. The variable contained platform-specific flags | |
needed to compile objects for shared libraries. Typically it included | |
a flag such as -fPIC for position independent code but also included | |
other flags needed on certain platforms. CMake 2.8.9 and higher | |
prefer instead to use the POSITION_INDEPENDENT_CODE target property to | |
determine what targets should be position independent, and new | |
undocumented platform variables to select flags while ignoring | |
CMAKE_SHARED_LIBRARY_<Lang>_FLAGS completely. | |
The default for either approach produces identical compilation flags, | |
but if a project modifies CMAKE_SHARED_LIBRARY_<Lang>_FLAGS from its | |
original value this policy determines which approach to use. | |
The OLD behavior for this policy is to ignore the | |
POSITION_INDEPENDENT_CODE property for all targets and use the | |
modified value of CMAKE_SHARED_LIBRARY_<Lang>_FLAGS for SHARED and | |
MODULE libraries. | |
The NEW behavior for this policy is to ignore | |
CMAKE_SHARED_LIBRARY_<Lang>_FLAGS whether it is modified or not and | |
honor the POSITION_INDEPENDENT_CODE target property. | |
This policy was introduced in CMake version 2.8.9. 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. | |
