I've cleaned the history.

Question: why removing mqtt tests in this PR ?

[hiergaut]

this cmake line list(FILTER test_srcs EXCLUDE REGEX ".*Mqtt\\.cpp$") did the job.
It removed Mqtt test if Mqtt library not found
The lines I commented are useless now because I use one directory per src module
We can rename the commit "Disable Mqtt tests" -> "Removed useless mqtt cmake removal"

[hiergaut]

Can I do the commit name change ?

Ok, makes sense.
Please :

• reword commit message as "[cmake] Remove dead code"
• in cmake, remove lines instead of commenting out
• in CHANGELOG, add entry [cmake] Remove dead code (#15)
