Make run-clang-tidy exclude a folder

Question

I want the python script run-clang-tidy to:

1. check files with .cc, .h, or .hpp extension
2. exclude anything in any folder called build

For example,

• check <project folder>/src/../include/solitaire/helloworld.h
• exclude <project folder>/build/<folder>/catch_reporters_all.hpp

I try the following:

cd <project folder>
# -- Make a `compiled_commands.json` -- #
mkdir build
cd build
cmake .. -DCMAKE_EXPORT_COMPILE_COMMANDS=ON
# -- Run in the build folder -- #
run-clang-tidy '^((?!/build/).)*(\.cc|\.h)$' \
    -header-filter '(\.cc|\.h|.hpp)$'

But it reports warning for:

<project folder>/build/_deps/catch2-src/src/catch2/
    ../catch2/reporters/catch_reporters_all.hpp:21:9:
error: header guard does not follow preferred style
    [llvm-header-guard,-warnings-as-errors]

Setting the -header-filter option to '^((?!/build/).)*(\.cc|\.h|.hpp)$' still doesn't work. That would exclude helloworld.h:

<project folder>/src/../include/solitaire/helloworld.h:1:1: 
error: header is missing header guard
    [llvm-header-guard,-warnings-as-errors]

What went wrong?
