Fix #9

@jcassette thanks for spotting and fixing this. We will review it internally and take the change.

Hi @jcassette, if you set PROJECT_VER in your top level CMakeList.txt, that is picked up and you won't fall to git describe path which you are.
We recommend you setting PROJECT_VER in project CMakeList.txt.

Example:

esp-insights/examples/minimal_diagnostics/CMakeLists.txt

Line 14 in 1d6bb17

set(PROJECT_VER "1.0")
