python must be on the PATH in order to be found automatically. Regarding the error, could you try using the mingw-builds of mingw-w64 and not the msys2 one, as detailed in the README.md? they are not the same.
Thanks for the help, but still was unable to build.
First when adding C:\msys64\usr\bin
to path, the build choose the python inside this path even if other python PATH are above.(which is weird)
PATH
D:\Python27
C:\msys64\usr\bin
C:\mingw64\bin
So still putting the path on the build (not sure if this may case some problem)
Also using the mingw-builds of the link on README. (and removed other gcc's path)

CMake Deprecation Warning at CMakeLists.txt:14 (cmake_policy):
The OLD behavior for policy CMP0051 will be removed from a future version
of CMake.
The cmake-policies(7) manual explains that the OLD behaviors of all
policies are deprecated and that a policy should be set to OLD only under
specific short-term circumstances. Projects should be ported to the NEW
behavior and not rely on setting a policy to OLD.

I see. This looks like this revision of LLVM does not work with 64 target of mingw-w64, hopefully fixed in later revisions. For now, the only option is to use the 32 bit target of mingw-w64.
The issue seems to have been fixed in LLVM: https://bugs.llvm.org/show_bug.cgi?id=38168
Yes, good find, will be fixed in later update or cherry pick this patch
my 32 bit target of mingw-w64 doesn't seem to work.
Sorry, do not know what is wrong
On Windows 10 / x64
First, it was giving me errors related to not finding LLVMBuild.txt file. After reading thought some issues it leave me to the problem related to python path.
so I added the path by flag:
cmake -G Ninja -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_WARNINGS=OFF -DPYTHON_EXECUTABLE=C://Python27//python.exe ../llvm
