The behavior was updated in 3.0 and is now described here: http://www.cmake.org/cmake/help/v3.0/variable/CMAKE_MAKE_PROGRAM.html In 2.8.12 and below we always stored CMAKE_MAKE_PROGRAM in CMakeCache.txt instead of waiting until build time to choose it. This was problematic because it was initialized before configuring the project so we could not know whether devenv had to be chosen for Intel Fortran support or not, so it always chose devenv if available. However, devenv does not work when using an alternative PlatformToolset with CMAKE_GENERATOR_TOOLSET: http://thread.gmane.org/gmane.comp.programming.tools.cmake.user/46795/focus=46969 Therefore we had to switch to build-time selection of the build tool. The change was mentioned in the 3.0 release notes: http://www.cmake.org/cmake/help/v3.0/release/3.0.0.html#other-changes "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."

You can also add -DCMAKE_MAKE_PROGRAM=/path/to/msbuild.exe to explicitly specify it. Once that is in CMakeCache.txt then it will always be used by "cmake --build". -Brad -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.
