In https://github.com/InfiniTimeOrg/InfiniTime/pull/1097 new font generation capabilites were added. Generalize the font creation to make it possible to reuse the `displayapp/fonts/CMakeLists.txt` file for `InfiniSim` and just add the new cmake file to the project and link against the new `infinitime_fonts` target. In the following a list of changes. Allow non-global installed `lv_font_conv` executable installed with ```sh npm install lv_font_conv@1.5.2 ``` In CMake we search for `lv_font_conv` executable. Add the found executable to the python script `generate.py`, to remove the need for `lv_font_conv` to be in the path. Search for `python3` executable, if CMake version 3.12 is available. Otherwise use `python` as hard coded executable. Instead of adding the generated fonts to `SOURCE_FILES` variable, create a static library `infinitime_fonts`. Link this library to the executables instead. Use `add_custom_target()` together with `add_custom_command()` to generate the font.c files once (like the original PR does).
