+Configure with clang as the compiler:
 
 ```sh
-./autogen.sh && ./configure CC=clang CXX=clang++
-make clean && bear --config src/.bear-tidy-config -- make -j $(nproc)
+cmake -B build -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_EXPORT_COMPILE_COMMANDS=ON
+cmake --build build -j $(nproc)
 ```

 To run clang-tidy on all source files:
 
 ```sh
-( cd ./src/ && run-clang-tidy  -j $(nproc) )
+( cd ./src/ && run-clang-tidy -p ../build -j $(nproc) )
 ```
 
 To run clang-tidy on the changed source lines:
 
 ```sh
-git diff | ( cd ./src/ && clang-tidy-diff -p2 -j $(nproc) )
