Then you can let Cygwin make to work well with all Windows compilers. -- Chiheng Xu Wuhan,China ___ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://www.cmake.org/mailman/listinfo/cmake

I just reread this. You need to use cmake _not_ for cygwin (i.e. normal Windows binary) if you want non-cygwin paths in your makefiles and cmake for cygwin if you want to use cygwin paths in your makefiles. Basically, your options are using the version of mingw provided with cygwin or using the CMake Windows version and remembering to specify mingw-make as the generator from the GUI. -- Cheers, Mike McQuaid http://mikemcquaid.com ___ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://www.cmake.org/mailman/listinfo/cmake

To do this you need to use a version of CMake compiled in Cygwin. I'm pretty
sure a binary package is available in the package manager.
