Additional context

I have tried to comment out "vcpkg_fixup_pkgconfig()", which seemed to work fine at that instance. But later I was facing issues with "find_package(io2d REQUIRED)"

It said that, it cant find io2d or io2dConfig.cmake files. Literally, I was up all night, for around 8 hours trying to solve this issue. Having no knowledge about vcpkg or cmake, I came here for help.

Thanks in advance.
