CGAL cmake на cygwin не работает

Question

Я пытаюсь скомпилировать CGAL 4.5 на cygwin (windows 7). У меня есть НКУ-ядро, GCC-г ++ и ГМП установлены, но когда я пытаюсь запустить CMake я получаю следующее сообщение об ошибке:

$ cmake . 
-- The CXX compiler identification is GNU 4.8.3 
CMake Error: Could not find cmake module file:/home/metalab/CGAL-4.5/CMakeFiles/2.8.11.2/CMakeCXXCompiler.cmake 
-- The C compiler identification is GNU 4.8.3 
CMake Error: Could not find cmake module file:/home/metalab/CGAL-4.5/CMakeFiles/2.8.11.2/CMakeCCompiler.cmake 
CMake Warning at /usr/share/cmake-2.8.11.2/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.

    It fails with the following output:

-- Configuring incomplete, errors occurred! 

я уже пробовал играть с CMAKE_LEGACY_CYGWIN_WIN32, но без успеха.

Я столкнулся с аналогичной ошибкой. Казак, похоже, не смог ничего найти от Кигвина.

Дело в том, что вам нужно запустить Cygwin-версию cmake. Если вы установили cmake из установщика, и он прошел под C:\Program Files, у вас неправильный cmake, и он не найдет больше всего, что он иначе найдет.
