cmake -DEVEL variable

[chrispbradley]

This cmake variable should be a boolean i.e., ON/OFF rather than take a number.

It takes anything it just needs to be defined. Making it a boolean just gives GUIs a hint as to what widget to display, which isn't any use here as once defined it cannot be changed.

does cmake require it to be set to something or is -DEVEL sufficient?

[chrispbradley]

I think it needs to be set to something. Having it as a boolean gives more clue as to what the possible values are. Having it set to anything is confusing as what value should be used. Every other variable that is a flag is boolean. I'm not sure what makes this one so special that it should be treated differently? @hsorby What happened about the build-a-thon? We changed the time specially for you?

It takes anything really, boolean or "Otto" if you like. Just "-DEVEL" is not sufficient (my last state). Change the docs to use a boolean if it suits you. Its "so special" since it's only job is to trigger the convenience process of copying the cmakedeveloper-config to the root folder. As cmake adds those vars to the cache if specified on the command line, it would probably be a good idea to remove whatever was set from the cache as soon as the template is copied. Cheerio
