fatal error: opencv2/core.hpp: No such file or directory compilation terminated in opencv4

Try installing the -dev
or -devel
package for OpenCV2 to get the header file.
sudo apt-get install libopencv-core-dev
on Debian and Ubuntu, and sudo yum install opencv-devel
on Fedora.
Once that's done, append $(pkg-config --cflags opencv)
to your compiler command:
export CC="gcc $(pkg-config --cflags opencv)"

In opencv4 while compiling code, I am getting this error:
fatal error: opencv2/core.hpp: No such file or directory compilation terminated.
I properly installed opencv4. Why am I getting an error?
