With CMake 2.8.7 and VS 2008, I can report the following findings:
(1) Starting out from within an empty build directory: "cmake .."
followed by "cmake --build ." configures/builds as expected.
(2) Tweaking CMakeLists.txt file only and leaving sources alone.
(3) "cmake --build ." rebuilds the ZERO_CHECK target and, thus,
updates the project file to reflect the changes from (2).
However, the corresponding target is not rebuilt and,
thus, does not reflect the changes from (2).
(4) A further "cmake --build ." does *nothing* - definitely.
(5) To get the concerned target rebuilt, I need to apply
David's hint, i.e. "cmake .&& cmake --build .", or
clean first, i.e. "cmake --build . --clean-first".
Can you provide an example and how to reproduce this?
I find it hard to believe that
cmake --build .
cmake --build .
will not build everything.
I get that the ZERO_TARGET does not get things to reload, but I don't
see how the second build would not get things up to date. It has
nothing to do with the project files depending on the targets. I assume
something really changed and there really needs to be a rebuild? What
type of thing are you changing in the CMakeLists.txt?
