Deprecated and Removed Features

  • The CMakeFiles/CMakeOutput.log and CMakeFiles/CMakeError.log files are no longer populated by CMake's built-in modules. cmake(1) no longer suggests looking at them after a CMake Error occurs. Information previously logged to those files is instead logged to the cmake-configure-log(7).

  • On CYGWIN, the undocumented CMAKE_LEGACY_CYGWIN_WIN32 mode for compatibility with CMake versions older than 2.8.4 has been removed.
