Do minor changes to cmake files

  * MacroLogFeature: Clarify that even if a package is found it will not be used if a feature is disabled
  * Use list append on CMAKE_MODULE_PATH to allow prepending it with toolchain file, which is used with conan recipe.
  * Use target_include_directories over include_directories for bundled zip headers - causes conflict in conan recipe.
