-Your development environment will need to have:
-
-- build essentials (gcc for Linux, clang for Mac)
-- cmake
-- python 3.\* and associated pip3/pip command
-- zstd
-
-Then, compilation on Unix machines will look something like:

-# Then decompress the contents
-> zstd -d -r --rm sdk

+```shell

-If all goes well, you will end up with a statically linked executable in `./build/FBX2glTF`.
+2. Init Autodesk SDK 2020.3.7
+```shell
