This is to try avoid some random "QXcbConnection: Could not connect to display :99" error
(that seems to occur especially during nightly build...)

BUG #48: Add '.lib' to 'optimized ' in cmake files

Closes #48

See merge request !84

FIXED do not interrupt all testing process if one test failed

See merge request !87

Integrates last develop changes (that include test on win7 runner)

FATAL_ERROR option in cmake generated a cmake error and stopped ci-test.sh, which returned with
exit value 1. The report to the dashboard was not submitted, resulting in a green dashboard but with
reduced number of tests pass.
The test job should not be interrupted by the first failed test and the dashboard should
show wichh test have failed.
