Having trouble installing WinAppleKey Driver from Github page - driver

I want to be able to capture input from the Fn and Eject keys on my Apple magic keyboard when using it with a Windows 10 machine. To do this, I came across an open source driver called WinAppleKey (https://github.com/samartzidis/WinAppleKey). The readme mentions a setup.msi file, which I could not locate in the repo after downloading it. So how do I actually install the driver?
I've tried running the WinAppleKey.sln file, which has not worked out despite having the latest versions of the WDK and SDK because of the following errors:

You may of already found it, but the setup.msi file is in the release files of the project and not the code source.
Here's where you can download it from : https://github.com/samartzidis/WinAppleKey/releases/tag/v1.0.9
You will just have to click on setup.msi to download it onto your PC.

MT5210 Native linking failed - Cannot build xamarin.ios (forms) app

EDIT (22/06-21): I went thru all my nugets one by one and found that the extra mtouch args. comes from the Xamarin.Firebase.iOS nugets. Someone over there has made the lib. so that it append some global mtouch flags. (the current stable version appends "-ObjC -lc++ -lsqlite3 -lz")
Since it dont seem to help to open an issue over there i must somehow make my lib. work with those flags. great...
I have a weird problem with building a ios forms app.
We have made a dll of a native library (openCV2) with some functions we need.
we have made a PoC that builds and runs just fine, but when we take it to the "real" app it cant build.
right before the build fails i see in the log:
/Library/Frameworks/Xamarin.iOS.framework/Versions/Current/bin/mtouch #/Users/xxx/Library/Caches/Xamarin/mtbs/builds/xxx.iOS/xxxx/obj/iPhone/Debug/device-builds/iphone11.2-14.6/response-file.rsp -v -v -v -v --gcc_flags=-ObjC
while on the PoC app the same line is:
/Library/Frameworks/Xamarin.iOS.framework/Versions/Current/bin/mtouch #/Users/xxx/Library/Caches/Xamarin/mtbs/builds/xxx.iOS/xxxx/obj/iPhone/Debug/device-builds/iphone11.2-14.6/response-file.rsp
i know the "-v -v -v -v" is from my additional mtouch args. but no where (that i can find) is the gcc_flags set and i cant find a way to remove it.
what i have tried with no luck:
linking Foundation framework in the additional mtouch args. linking
Foundation framework in the LinkWithAttribues.cs file in the binding
project none, sdk-only and all linking. looked at diffrenses in the
project files made all the changes i can think of in the LinkWith
file eg. linker flags, smart linking c++ and the like. tried with and
w/o this linker flag L/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/iphonesimulator/ -L/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/iphoneos -Wl,-rpath -Wl,#executable_path/Frameworks
made sure the code in the implementation and PoC is 100% the same
made the iOS build options 100% the same in project and PoC
installed the xamarin.swift nuget
tried both 4.8 and 5.0 xamarin forms
im running
vs for mac 8.10 (for binding project)
vs2019 16.10.1 (for app building)
xamarin.ios 14.19 on both
does anyone have a idea on what is going wrong here?
Im at the end of my rope, any help or ideas on where to look would be greatly appricieted.
here is the complete "failing" build log:

Xamarin iOS Linking Failed Problem While Building

The application is ready for Xamarin IOS.
Yesterday there was no problem. I did visual studio update for hot restart to 16.7.3.
Today when I turn it on, I am remote to the mac, but when I say build, I get linking failed errors like the following, about 33.
I haven't installed any nuget packages etc.
It took me a day to undo the last changes I made.
It builds when not connected to the Mac but when I connect to the mac I get these errors anyway.
I can't figure it out. Can you help me?
This is the project output while building:

How does Clang find it's default sysroot / target triple? (clang-tidy has stopped working)

Background:
On a Windows 10 PC, I have a c++ codebase. Using CMAKE I generate an Mingw-w64 project (using Eclipse IDE) and a Visual Studio 2017 project. I like compiling my projects with different build systems as each gives different warnings and errors.
As part of the Mingw build, I can enable clang-tidy checks using CMAKE's CXX_CLANG_TIDY. This works well, producing a co-compile showing many interesting warnings from clang-tidy.
When I installed mingw-w64, llvm and VS I was careful not to allow these to populate the PATH environment variable, so a regular command prompt won't run gcc, clang, or CL or any associated tools. The environment is set up by a batch file before launching Eclipse or Visual Studio.
This has worked well for years (I'm still using clang 7.0.1). Both IDE's compile the same code base just fine...
Until I upgrade to Visual Studio 2019, including it's own copy of clang 10.0.0.
Now, my original clang 7.0.1 has stopped working! As I only use clang-tidy it took a while to narrow this down, but the original clang is looking for the system headers in the new clang's include location. The headers it finds are too new and the build fails.
I have found many things to try on SO and elsewhere (although any pointers are welcome) like supplying a --sysroot switch, so this question is more specific:
Question:
When there are no apparent environment variables to point to a specific clang location, where does clang find it's default target triple and therefore it's -internal-isystem paths? Why does my previously-working clang installation now look for it's system headers in a more recently installed clang location?
With a Windows command prompt:

#error STL1000: Unexpected compiler version, expected Clang 9.0.0 or newer.
Where C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.26.28801\include is the installed-only-today clang 10.0.0 location, so clearly not compiled into clang.exe.
Where does clang get it's defaults from?

The only "ground truth" is the code of clang itself.
With multiple versions of MSVC installed, clang will use different tricks to setup environment when initializing MSVC toolchain driver (see MSVCToolChain::MSVCToolChain() at the link above)
To solve a similar case I used VCToolsInstallDir environment variable to direct clang to old MSVC include paths.

MobileVLCKit for iOS fails to build

i am following the instructions in https://wiki.videolan.org/VLCKit/ to build a MobileVLCKit.framework for my project. because i have to make minor tweaks to source, i cannot use a ready made build.
i run sudo ./buildMobileVLCKit.sh -vd
and am stuck at
The following build commands failed:

an inspection confirms that i do not have this directory at all VLCKit/MobileVLCKit/ImportedSources/vlc/install-ios-OS
why?
my environment: mavericks, xcode 5.1, ios SDK 7.1
