CLANG_FORMAT_LOC
The path to the bin dir for LLVM can be used for both clang-cl.exe and
clang-format.exe. Changing this will reduce the amount of environment
variables in play, leading to better long term quality.
Done in batch script because Powershell requires execution policy to be
changed to run scripts. Therefore batch files are considered to have a
lower barrier for entry.
Currently the variable expansion sometimes doesn't work when done over
two variables. Inlining the ~dp0 call along with \..\..\ seems to work.
Testing leads me to believe that the Windows command prompt caches
things in a weird way.
The old build scripts used hard coded directory paths, didn't check if
the paths actually existed and didn't differentiate between compiling,
deploying libraries and packaging for release.
The new build scripts are split into three different files. They are all
longer than the old build scripts, but most of the extra lines are
error checking, which the old one lacked.
It was considered writing the build scripts in another language like
Python or Powershell, but the relatively small size of the project and
unlikelihood of the build systems needing to grow massively means that a
very simple imperative language like the Microsoft scripting language is
fine.
