llvm dev - Apr 2020 - Getting the LLVM includes to be recognized

I am using the following cmake input :
c:\Users\Administrator\Documents\programming\cmake-hello-clang\build>"c:\Program
 Files\CMake\bin\cmake.exe" -GNinja -DCMAKE_MODULE_PATH="C:/Program
Files
(x86)/
LLVM/lib/cmake" -DLLVM_INCLUDE_DIRS="C:/Program Files
(x86)/LLVM/include" ..

however when Ninja is run I get.

c:\Users\Administrator\Documents\programming\cmake-hello-clang\build>ninja
[1/2] Building CXX object CMakeFiles/myTool.dir/main.cpp.obj

You seem to have added a target "myTool" to the LLVM sources. You must
tell CMake to add the required include path, etc. For instance, using

   target_link_libraries(myTool PUBLIC LLVMCore)

Not that alone will not be sufficient. I recommend Google'ing a
tutorial for what you are doing.

Btw, it is not recommended to work under the Administrator account.
