ENH: UNIX, CYGWIN, WIN32, APPLE, QNXNTO and BEOS are not longer set in cmMakefile.cxx, but now in the platform files and are now valid for the target platform, not the host platform. New variables CMAKE_HOST_WIN32, CMAKE_HOST_UNIX, CMAKE_HOST_APPLE and CMAKE_HOST_CYGWIN have been added in cmMakefile.cxx (...and have now to be used in all cmake files which are executed before CMakeSystemSpecificInformation.cmake is loaded). For compatibility the old set is set to the new one in CMakeDetermineSystem.cmake and reset before the system platform files are loaded, so custom language or compiler modules which use these should still work.

BUG: Fixed cygwin module creation rules. Modules should not have the "cyg" prefix by default. Removd soname flags from creation rules because they are never used on this platform. 2006-02-19 13:34:22 -05:00			`SET(CMAKE_SHARED_MODULE_PREFIX "lib")`

Do not find cyg.dll on Cygwin While Cygwin supports linking directly to .dll files, the behavior is now discouraged. All Cygwin packages now provide import libraries of the form lib.dll.a and CMake has built the import libraries for years. We believe it is now safe to stop explicitly searching for .dll files because their import libraries will always be available when the corresponding header files are available. Users can always set find_library cache entries to point at a .dll file by hand if they really must use one. Change based on patch from issue #10122. 2010-01-13 14:12:29 -05:00			`SET(CMAKE_FIND_LIBRARY_PREFIXES "lib")`
