Finally maybe fix FetchContent?

This is like a year and a half overdue, sorry about that @TheMariday ... especially if the fix really is this simple ...

The test case: https://github.com/TheMariday/pocketsphinx_fetch_content_example/blob/main/CMakeLists.txt

This should fix the fetch content issue! Only thing to mention in my findings is that ps will only be able to find the models after the install step which I think is intended functionality. My only wondering is if the POCKETSPHINX_PATH environment variable could be set to the build directory prior to the install step to allow applications to find the models directly after build. I have not tested this however!

(back from vacation) that does seem like a good idea - is the FetchContent use case generally used to build things and run them from the build directory? In general I don't like requiring people to "install" things if not necessary...
