+
+Use when:
+
+* adding new `.cpp` files
+* modifying `CMakeLists.txt`
+* changing presets
+
+```powershell
+cmake --preset windows-debug
+```
+
+## What it does
+
+* Reads `CMakePresets.json`
+* Loads vcpkg toolchain
+* Finds installed libraries
+* Generates Ninja build files
+
+---
+
+# 2. Build Project
+
+Use after changing C++ code.
+
+```powershell
+cmake --build --preset windows-debug
+```
+
+## What it does
+

+* strange errors appear
+
+```powershell
+cmake --preset windows-debug --fresh
+cmake --build --preset windows-debug
+```
