[cmake-developers] Debug through config/gen inside Visual Studio

[csiga.biga at aol.com]

Hi everyone!

I wanted to see how CMake actually Works under the covers to see how much actual work it would take to implement a feature I proposed quite a while ago. My problem is that even though I built CMake with the  „Visual Studio 14 2015 Win64” generator, I setup the cmake target to use:

Command Arguments: -G "NMake Makefiles" C:\Users\Matty\OneDrive\Develop\Tests\CMake\CMake_example
Working Directory: C:\Users\Matty\Build\CMake_Example\NMake

There is even an option to create new environtment variables prior to debugging. My problem is that even though I checked what vcvarsall.bat creates on the command line, I exported the same variables, but the compiler fails according to CMake (see at the end).

How do you setup Visual Studio to debug through a config/gen process?

Thanks in advance,
Máté
