cmake: Generate better pkg-config file for SYSROOT builds under CMake I recently fixed this for Autotools but said that fixing this for CMake was not feasible due to it using `find_package` rather than `pkg_check_modules`. I then thought about it and couldn't find any reason why CMake couldn't try `pkg_check_modules` first and then fall back to `find_package`, as that's basically what Autotools does. I had wanted to use the linker flags generated by CMake when it does fall back to `find_package`, but it only returns direct paths to the libraries, as opposed to `-l` flags. Baking these library paths into the pkg-config and xml2-config files would break static linking and cross-compiling, so I've stuck with the `-l` flags we already have. There is no need to set `CMAKE_REQUIRED_LIBRARIES` because we already add the dependencies to the library target.
