+ normal Visual Studio solution file, but it is not always kept up-to-date
+ and will soon be deprecated in favor of the multi-platform generator
+ CMake.</li>
+ <li>If CMake is installed then the most simple way is to just start the
+ CMake GUI, select the directory where you have LLVM extracted to, and
+ the default options should all be fine. The one option you may really
+ want to change, regardless of anything else, might be the
+ CMAKE_INSTALL_PREFIX setting to select a directory to INSTALL to once
+ compiling is complete.</li>
+ <li>If you use CMake to generate the Visual Studio solution and project
+ files, then the Solution will have a few extra options compared to the
+ current included one. The projects may still be built individually, but
+ to build them all do not just select all of them in batch build (as some
+ are meant as configuration projects), but rather select and build just
+ the ALL_BUILD project to build everything, or the INSTALL project, which
+ first builds the ALL_BUILD project, then installs the LLVM headers, libs,
+ and other useful things to the directory set by the CMAKE_INSTALL_PREFIX
+ setting when you first configured CMake.</li>
