Subject: [PATCH] CMake: fix time check typo (fixes build failure w/ GCC 12)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Without this fixed check, we get a build failure with GCC 12:
```
/var/tmp/portage/sci-chemistry/openbabel-3.1.1_p20210225/work/openbabel-08e23f39b0cc39b4eebd937a5a2ffc1a7bac3e1b/include/openbabel/obutil.h:65:14: error: ‘clock’ was not declared in this scope; did you mean ‘clock_t’?
   65 |       start= clock();
      |              ^~~~~
      |              clock_t
```
