Hi Chirag,

Did you follow the instructions in the CMake output and 'Add the
installation prefix of "QuantLib" to CMAKE_PREFIX_PATH or set
"QuantLib_DIR" to a directory containing one of the above files'?

If C:/local/QuantLib-1.24/cmake-build-debug-visualstudio2017 is your CMake
build directory, then the 'above files' will be found in the cmake
directory under that build directory.

If that doesn't work then the best I can do is point you to the
documentation on CMake config mode[1] and wish you luck, as I won't be able
to offer much further help remotely.

By the way, the quantlib-vcpkg-example repo that you found is an example of
how to link your project to QuantLib installed through vcpkg, which you
haven't used. If you'd like to, you can try out vcpkg, and it may make your
life easier in the long run, but be aware that it has a learning curve of
its own to grapple with first.
