Hi,
FindCygwin.cmake try to find Cygwin installation as follows: FIND_PATH(CYGWIN_INSTALL_PATH cygwin.bat "C:/Cygwin" "[HKEY_LOCAL_MACHINE\\SOFTWARE\\Cygnus Solutions\\Cygwin\\mounts v2\\/;native]" ) Unfortunately, recent versions of Cygwin do not install this registry key anymore, but this one: [HKEY_LOCAL_MACHINE\SOFTWARE\Cygwin\setup] "rootdir"="D:\\cygwin" Best regards, Fabrice Aeschbacher _______________________________________________ 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
