Hi David,

from QtCreator/Project you could rerun cmake and there you could pass the argument

     -Dkst_pch=OFF

There you could also see all the other options.


But when you wanna compile with MSVC you could use Visual Studio for developing.
I never use nmake for building Kst: developing with Studio, deploying with mingw.

Open a Visual Studio shell, add the path to qmake (set PATH=C:\Qt\...\bin;%PATH%),
create a build folder on the same level as the Kst checkout
and call within the build folder

     cmake ..\kst\cmake -G"Visual Studio 10"

Open the solution file kst.sln from command line.
I'm sure this will work.

To start over the best way is to completely clean the build folder.
