Move the Version member to the top cmLocalVisualStudioGenerator class
and set it consistently for instances created by all the global
generator versions. Use an enumeration type with values scaled by a
factor of 10 so we can handle VS 7.1 without out-of-order numbers.
VS 7.1 support for SuppressStartupBanner was broken by commit 25116a3c
(Fix CMAKE_VERBOSE_MAKEFILE for VS10 vcxproj files, 2011-10-11) because
it assumed comparison of VS version numbers works. Now it does.
To get rc defines to work in the VS10 IDE requires \" when
constructing PreprocessorDefinitions strings. This is different
than defines for cl.
Also, per-file rc defines were not being generated. Fix that, too.
Look for the "/threads", "/libs:dll", and "/dbglibs" flags and convert
them to the proper RuntimeLibrary attribute value in the IDE. This is
a 3-to-1 flag mapping and such needs special handling in the parser.
This converts the CMake license to a pure 3-clause OSI-approved BSD
License. We drop the previous license clause requiring modified
versions to be plainly marked. We also update the CMake copyright to
cover the full development time range.
