Hi I am building on Visual Studio Community 2019 amd64. Against llvm 14.05, I am getting a lot of missing symbols and warnings. To save you grief I have just included the errors. I would love to get this working on my windows rig (our linux platform is in pipeline). Can you give me pointers as to where I have gone off the rails?
I have tried branch v_0.8 and main to no avail.

The only change I have done is in the main CMakeLists file:
#find_program(LLVM_CONFIG_PATH "${INSIGHTS_LLVM_CONFIG}")
set(LLVM_CONFIG_PATH "C:\LLVM14.05\bin\llvm-config")

Windows sdk 10.0.19041.0
Compiler version : 19.29.30146.0
