Closes #469
 2021-01-08 18:20:54 +01:00
Julien Schueller 8f004b353a CMake: Bump minimum version to 3.2 
Newer cmake issues a warning when required version is < 3.
Version 3.2 should be old enough (eg ubuntu 16.04 has version 3.5).

Igor Zhuravlov 42ec867e7f comments fixed: typos 2021-01-07 11:20:03 +10:00
Igor Zhuravlov 020d538c9f Revert "filenames fixed: extension to lower case" 
This reverts commit ae465ccbac.

That commit to revert was wrong: an upper-case file extension enables
preprocessing (see https://gcc.gnu.org/onlinedocs/gfortran/Preprocessing-Options.html)
which is required to parse #if defined(_OPENMP) directives correctly.
