[CMake] Different behaviour between cmake-gui vs cmake using command line mode

[David Cole]

For the same behavior as cmake-gui, use the same build directory. (For
the command line app "cmake", the current working directory is the
build directory... The argument you give the first time you run it is
the source directory.)

Try:

>> cd C:/Arnault/CMT2/test/A/build
>> cmake ..
>> cmake --build .


HTH,
David
