[restored issue] - Indentation errors

Hi, we are trying to validate Chameleon with HIP using a newly created docker image based on Ubuntu 22.04 and gcc 11.3. We meet the following error trying to build with test_fembem

/builds/satanas-atos/chameleon/testing/test_fembem/src/testHMAT.c:112:3: error: this ‘if’ clause does not guard... [-Werror=misleading-indentation]
