Good day all, (Not sure if most people already know this, but I thought it might be useful to record this "somewhere on the Internet" for future reference)
Visual Studio sometimes reports errors from custom commands (or custom targets) even though they exit with zero, if they output certain strings. An example output string that would trigger an error is "hejsan: error : ". The string at least contains a colon, after that the string "error" (without the quotes) and after that another colon. This effect can be recreated by creating a custom command (within a Visual Studio project) that just prints that string. Also, the following little cmake-project can be used to illustrate this effect. Notice the difference between target1 and target2 below. This is not ideal for us. Sometimes our code prints stuff like that, even though there is no real error. Example: Test code that *checks* that a certain asserts *fires* at some condition (a *negative* test). The assert may very well print a string that Visual Studio triggers on. I am not sure whether this is to be considered a cmake issue at all?
