### PGO Build (Ultra optimized build)
#### Part 1 (generate profile data)
```bash
mkdir build
cd build
cmake .. -G Ninja \
-DENABLE_NOGUI=ON \
-DENABLE_QT=OFF \
-DENABLE_HEADLESS=ON \
-DENABLE_ALSA=OFF \
-DENABLE_PULSEAUDIO=OFF \
-DENABLE_VULKAN=ON \
-DFASTLOG=OFF \
-DENABLE_AUTOUPDATE=OFF \
-DENABLE_SDL=OFF \
-DENCODE_FRAMEDUMPS=ON \
-DENABLE_LLVM=OFF \
-DENABLE_X11=OFF \
-DCMAKE_BUILD_TYPE=Release \
-DENABLE_EGL=OFF \
-DENABLE_ANALYTICS=OFF \
-DUSE_RETRO_ACHIEVEMENTS=OFF \
-DUSE_DISCORD_PRESENCE=OFF \
-DCMAKE_CXX_FLAGS="-march=native -mtune=native -flto -O3 -pipe -fprofile-generate" \
-DCMAKE_C_FLAGS="-march=native -mtune=native -flto -O3 -pipe -fprofile-generate" \
-DCMAKE_EXE_LINKER_FLAGS="-flto -fprofile-generate" \

-DCMAKE_MODULE_LINKER_FLAGS="-flto -fprofile-generate" \
-DCMAKE_INTERPROCEDURAL_OPTIMIZATION=ON
ninja -j $(nproc)
```
**After building this version, run for a bit and play to generate profiling data, the more, the better.**
#### Part 2 (Merge profile data)
```bash
llvm-profdata merge -output=default.profdata *.profraw
```
#### Part 3 (Build with profile data)
```bash
cd build
cmake .. -G Ninja \
-DENABLE_NOGUI=ON \
-DENABLE_QT=OFF \
-DENABLE_HEADLESS=ON \
-DENABLE_ALSA=OFF \
-DENABLE_PULSEAUDIO=OFF \
