cppflow: CppFlow/ops.h missing

Following the installation instructions, when running ‘make’ I have this error:

/Users/david/Desktop/cppflow/examples/load_model/main.cpp:3:10: fatal error: 'cppflow/ops.h' file not found #include "cppflow/ops.h"

I might be messing a step?

About this issue

btw seems like i found a way to fix it i used commands

git clone https://github.com/serizba/cppflow
cd cppflow
mkdir build
cd build
cmake -DBUILD_EXAMPLES=OFF ..
make -j
sudo make install

and it installed successfully
