Re: [Plplot-devel] Spurious warnings on Cygwin should now be gone

[Arjen M. <Arj...@de...>]

Hi Alan,



Well, that was easy and it brought up the warning immediately:



-- Explicitly setting policy CMP0051 to OLD

-- Explicitly setting policy CMP0052 to OLD

-- Explicitly setting policy CMP0053 to OLD

-- Explicitly setting policy CMP0054 to OLD

CMake Warning at /usr/share/cmake-3.1.2/Modules/Platform/CYGWIN.cmake:15 (message):

  CMake no longer defines WIN32 on Cygwin!



  (1) If you are just trying to build this project, ignore this warning or

  quiet it by setting CMAKE_LEGACY_CYGWIN_WIN32=0 in your environment or in

  the CMake cache.  If later configuration or build errors occur then this

  project may have been written under the assumption that Cygwin is WIN32.

  In that case, set CMAKE_LEGACY_CYGWIN_WIN32=1 instead.



  (2) If you are developing this project, add the line



    set(CMAKE_LEGACY_CYGWIN_WIN32 0) # Remove when CMake >= 2.8.4 is required



  at the top of your top-level CMakeLists.txt file or set the minimum

  required version of CMake to 2.8.4 or higher.  Then teach your project to

  build on Cygwin without WIN32.

Call Stack (most recent call first):

  /usr/share/cmake-3.1.2/Modules/CMakeSystemSpecificInformation.cmake:36 (include)

  CMakeLists.txt:39 (project)
