The

-IM:\Development\x64\LLVM\tools\clang\lib\StaticAnalyzer\Frontend\..\Checkers

above should take care of finding Checkers.inc. Can you verify that
Checkers.inc exists in

M:\Development\x64\LLVM\tools\clang\lib\StaticAnalyzer\Checkers

?

BTW, I just built LLVM+Clang with MinGW 32 bits using MSYS.

Oh, there is something fishy on the usage of add_dependencies on those
CMakeLists.txt files. Please see if this two patches allows you to move
a bit forward on the build:
