it will look for utfcpp in the standard system paths, UTFCPP_PATH,
and lib/utfcpp/v2_0/source.
This allows the use of utfcpp in:
* standard locations such as /usr/include on distributions shipping
utfcpp
* custom locations for users via UTFCPP_PATH
* the source tree using the default location of the utfcpp
git submodule, .i.e lib/utfcpp/v2_0
