Hello,

I use Visual Studio generator, and it produces four targets (-\> 4 projects in VS), including ZERO\_CHECK and INSTALL. There is nothing about these points the the generator documentation.

With a know search engine, I made the following search:  
“ZERO\_CHECK” site:[https://cmake.org/cmake/help/](https://cmake.org/cmake/help/)

I found only two entries, regarding a bug in the ZERO\_CHECK logic for XCode.  
I didn’t search for INSTALL, because the word is too generic.

So there is no documentation for ZERO\_CHECK and INSTALL ?

PS: In **Professional CMake** book, INSTALL is tackled in the chapter **Deployment And Dependencies \> Installing \> Base Install Location** , and ZERO\_CHECK in **Builds In Depth \> Apple features \> Limitations**.
