Updated to new SDK, cant run cmake now for C on Windows

I haven't changed anything, I just tried to compile my code under the new version of the SDK and I'm getting this error:
CMake Error at CMakeLists.txt:31 (project):

The code in the file is this for lines 29/30

set(PLAYDATE_GAME_NAME TestGame)
set(PLAYDATE_GAME_DEVICE TestGame_DEVICE)

Line 31 says:

project(${PLAYDATE_GAME_NAME} C ASM)

That line has always worked. I tried a different app/game and it gives the same error in the same place. Anyone know what the new SDK did? This is compiling on C

did you redo cmake .. before recompiling ? with each new sdk update you need todo that. Unless thats whats actually generating the error

There are some new changes that may break cached CMake files. I'd delete your build folder and build clean. If you still are having troubles, let us know.
