+### OpenCV 4.11.0
+
+**1. Install build dependencies** 
+```bash
+sudo apt update
+sudo apt install -y build-essential cmake git pkg-config unzip wget
+sudo apt install -y libgtk-3-dev libavcodec-dev libavformat-dev libswscale-dev
+sudo apt install -y libjpeg-dev libpng-dev libtiff-dev
+```
+
+**2. Download OpenCV 4.11.0 source**
+```bash
+cd /tmp
+wget -O opencv-4.11.0.zip https://github.com/opencv/opencv/archive/refs/tags/4.11.0.zip
+unzip opencv-4.11.0.zip
+```
+
+**3. Configure build**
+```bash
+cd /tmp/opencv-4.11.0
+mkdir build
+cd build
+
+cmake -S .. -B . \
+ -DCMAKE_BUILD_TYPE=Release \
+ -DCMAKE_INSTALL_PREFIX=/opt/opencv-4.11.0 \
+ -DBUILD_opencv_python3=OFF \
+ -DBUILD_opencv_python2=OFF \
+ -DBUILD_TESTS=OFF \
+ -DBUILD_PERF_TESTS=OFF \
+ -DBUILD_EXAMPLES=OFF
+ ```
+
+**4. Build and install**
+```bash
+cmake --build . --parallel "$(nproc)"
+sudo cmake --install .
+```
+
+**5. Set OPENCV_INSTALL_ROOT permanently for interactive shells**
+```bash
+echo 'export OPENCV_INSTALL_ROOT=/opt/opencv-4.11.0' >> ~/.bashrc
+source ~/.bashrc
+```
+
+Verify:
+```bash
+echo $OPENCV_INSTALL_ROOT
+ls $OPENCV_INSTALL_ROOT
+```
+
+You should see folders like:
+- bin
+- include
+- Lib
+- share
+or similar.
+
+
+**6. System library path setup**
+If the sample executable cannot find OpenCV shared libraries at runtime, add:
+```bash
+export LD_LIBRARY_PATH=/opt/opencv-4.11.0/lib:$LD_LIBRARY_PATH
+```
