pybind11.h: No such file or directory

Question

I am trying to compile Deepstream 6.0 Python bindings. My guess it that the issue not related to Deepstream, but to general C/C++ compiling issues:

sudo apt install -y git python-dev python3 python3-pip python3.6-dev python3.8-dev cmake g++ build-essential \
    libglib2.0-dev libglib2.0-dev-bin python-gi-dev libtool m4 autoconf automake
sudo apt-get -y install pybind11-dev
git clone https://github.com/NVIDIA-AI-IOT/deepstream_python_apps.git
cd deepstream_python_apps
git checkout v1.1.0
cd bindings
mkdir build
cd build
cmake ..
make

I encounter the error:

ubuntu@ip-x-x-x-x:~/pycharm/libs/deepstream_python_apps/bindings/build$ cmake ..

If I look for pybind11.h I can find it in:

/usr/include/pybind11/pybind11.h

you need to install the gst-python dependency as stated in the README.

make sure to pull all the git submodules beforehand, otherwise the 3rdparty/gst-python folder might be empty for you.
