Subject: [PATCH] cmake: fix python version comparison due to whitespace

Previously, there was warnings such as:
```
CMake Warning at CMakeLists.txt:131 (message):
  /usr/bin/python3.11 --version is 3.11.7

  , which is less then the minimum required, 3.5.2; disabling building of
  API.
```
The presence of whitespace turned VERSION_LESS into a lexicographic comparison, so python versions >=3.10 would incorrectly compare less.

This change should fix this.
