[CMake] What is --build-two-config good for

[Torsten Robitzki]

Hello,
can someone of you tell me, what the purpose of the CTest —build-two-config command line option is? The documentation says, that it is part of the CTest Build and Test Mode and that it will cause CTest to run CMake twice. I’ve checked the code and yes, it does exactly this.

But why? What could be the reason to run CMake twice, when running CMake in a test from CTest?

Best regards,

Torsten
