I have created a Jenkins pipeline that covers both windows and linux.

However it appears that cmakeBuild does not use buildType correctly for visual studio

For Linux is correctly adds -DCMAKE_BUILD_TYPE=Debug or Release in the configure step

However for windows the CMAKE_BUILD_TYPE variable is ignored:

17:47:24    Manually-specified variables were not used by the project:
17:47:24  
17:47:24      CMAKE_BUILD_TYPE

And subsequently in the --build step, the --config is unused. Resulting in a Debug-by-default build with the visual studio generator.

-config Debug or -config Release (depending on buildType should be added to the --build phase for windows (and CMAKE_BUILD_TYPE should not be used for visual studio generator)

The current workaround to this is adding --config Debug/Release explicitly in the steps:

steps: [[args: '--config Debug', withCmake: true]]

Which of course is less than ideal if the buildType property is available.
