[CMake] How to start CMake from scratch

[Christian Arnault]

Hi

[I am on windows]

If I use cmake-gui to build my project, it starts asking me for the 
build directory. Which is OK!

(my project is named "B", it stands in "test/B", where there is a 
"test/B/CMakeLists.txt" and I want to build into "test/B/build")

Now, if I use command interface CMake as follows (with an empty build 
directory):

>  cd test
>  cmake B --build B\build
CMake Error: The source directory "C:/Arnault/CMT2/test/B/build" does not appear to contain CMakeLists.txt.
Specify --help for usage, or press the help button on the CMake GUI.


If I first run cmake-gui, and specify the build directory, it's OK and 
it properly populates the cache.

if now, I redo (command line but with a build directory already populated) :

>  cmake B --build B\build


it's all ok now!!

Question: How to start a build from scratch, using the command line, and 
specifying a build out-the-source ?

Thanks a lot for your help...

Cheers
Christian
