Is the build tree produced from scratch with 3.2.0 or is it left from 2.8.12? Does the CMakeCache.txt file contain an entry for CMAKE_MAKE_PROGRAM?

See documentation of that variable here:

http://www.cmake.org/cmake/help/v3.2/variable/CMAKE_MAKE_PROGRAM.html [^]

and the change in default behavior as of 3.0:

http://www.cmake.org/cmake/help/v3.2/release/3.0.html [^]
"When using Visual Studio generators, CMake and CTest no longer require CMAKE_MAKE_PROGRAM to be located up front. Selection of the proper msbuild or devenv tool is now performed as late as possible when the solution (.sln) file is available so it can depend on project content."

Yes. It's built from scratch.

No. I checked CMakeCache.txt from CMake 2.8 and it pointed to "D:/Programy/Microsoft Visual Studio 9.0/Common7/IDE/VCExpress.exe". I copypasted that into 3.2-rc2, but no avail.

The problem isn't that CMake fails to run the build tool. The build tool is run just fine and the compilation runs and the program gets compiled just fine. The only problem is that there's no output. It's as if cmake.exe's output was redirected to Windows' equivalent of /dev/null.

Re 0015437:0038191: CMake >= 3.0 detect and run the build tool under the hood, and also just shares the pipes directly instead of buffering the output as <= 2.8.12 did.

I cannot reproduce this. I see all the build output.

For debugging, please add the line

message(STATUS "CMAKE_VS_DEVENV_COMMAND=[${CMAKE_VS_DEVENV_COMMAND}]")

to your CMake code. What does that print?

Re 0015437:0038192: And for completeness:

CMAKE_VS_DEVENV_COMMAND=[D:/Programy/Microsoft Visual Studio 9.0/Common7/IDE/VCExpress.exe]
CMAKE_MAKE_PROGRAM=[D:/Programy/Microsoft Visual Studio 9.0/Common7/IDE/VCExpress.exe]

The project I'm working on is open-source. Would it help if I provided a link to it?

Re 0015437:0038194: That is the expected output, thanks.

I doubt this is specific to the project you're building, but certainly a link wouldn't hurt.

I also doubt that, but anything is possible.

For completness: the output is present when I compile the project from Visual Studio's UI, of course.

I've reproduced this specifically with Visual Studio Express using VCExpress.exe as the build tool. It does not happen with devenv.com from the professional versions. It looks like VCExpress.exe itself has no output when used from an interactive console. The only way to convince it to produce output is to set an environment variable (vsconsoleoutput=1), which "cmake --build" already does, and also to have the output go somewhere other than the console.

When CMake 3.0 switched to directly sharing the console pipes with the build tool (primarily to get msbuild color output to work) it broke a workaround we had for VCExpress accidentally.

I've committed a fix that restores the workaround:
