Hide custom command .rule files inside the CMakeFiles directory. Ensure
a short, deterministic, and unique name by using a hash of the directory
path containing the output file. Preserve the file name so the entry in
the IDE is human-readable. Clarify the comment that explains why the
rule file must be created on disk.
Rename cmGlobalGenerator::GetCMakeCFG{InitDirectory => IntDir} to
have a shorter name without a typo. Add a 'const' qualifier since
the method is only for lookup and never needs to modify anything.
The Express Edition does not come with 64-bit tools, but one can install
the "Microsoft Windows SDK v7.1" to get them. Detect this case and
check for the SDK. If found, set PlatformToolset to use the SDK tools.
Otherwise, fail with a concise and informative error.
VS 10 provides $(Configuration) and $(ConfigurationName) but only the
former is documented so we prefer it. This also makes CMAKE_CFG_INTDIR
consistent with its documentation. See issue #9916.
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.
This method returns the registry key
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\<version>
A protected GetIDEVersion method retrieves the version-specific part of
the key name.
