Finding wxWidgets on CMake with CMAKE_PREFIX_PATH

I am trying to use find_package to find wxWidgets, which is placed inside the location pointed to my CMAKE_PREFIX_PATH, however I am not succeeding.

If I set the environment variable WXWIDGETS_ROOT_DIR to the wxWidgets installation, then all works fine. However, if I set CMAKE_PREFIX_PATH to the folder containing my folder wxWidgets-3.1.4, wx is not found.

How can I fix this? Where is there documentation on the fact that WXWIDGETS_ROOT_DIR needs to be used? I only found this out through another stack overflow post.

My CMakeLists.txt:
