Pkg-config file

[1480c1]

A pkg-confg (.pc) file would be nice for better integration within the open source ecosystem by way of providing an easier way to declare what CFLAGS and LDFLAGS are needed for proper compilation. This would help prevent needing the user to supply them manually, such as through --extra-cflags="-fopenmp -I../Video-Super-Resolution-Library/install/include/" and --extra-libs='-lraisr -lstdc++ -lippcore -lippvm -lipps -lippi'.

A basic pkg-config file can be observed at https://people.freedesktop.org/~dbn/pkg-config-guide.html and can be configured/generated by cmake as mentioned in https://www.scivision.dev/cmake-generate-pkg-config/
