CMake initial cache file's settings being ignored: its worked before

Question

I'm worried that my Windows 8.1 OS may have been hacked because I can't think of any other reason for why this problem is happening.

Here's the contents of my cache file which has worked before:

set(WITH_SDL ON CACHE BOOL "")
set(WITH_AUDIO ON CACHE BOOL "")

set(WITH_MOVIES OFF CACHE BOOL "")
set(WITH_FREETYPE2 OFF CACHE BOOL "")
set(WITH_LUAJIT OFF CACHE BOOL "")
set(WITH_LIBAV OFF CACHE BOOL "")
set(BUILD_ANIMVIEWER OFF CACHE BOOL "")
set(BUILD_MAPEDITOR OFF CACHE BOOL "")

set(LUA_INCLUDE_DIR "C:/Program Files (x86)/Lua/5.3.0/include" CACHE PATH "")
set(LUA_LIBRARY "C:/Program Files (x86)/Lua/5.3.0/lua53.lib" CACHE FILEPATH "")
set(SDL_INCLUDE_DIR "C:/Users/Joseph/Programming/Github/Libraries/SDL2-2.0.3/include" CACHE PATH "")
set(SDL_LIBRARY "C:/Users/Joseph/Programming/Github/Libraries/SDL2-2.0.3/lib/x86/SDL2.lib" CACHE FILEPATH "")
set(SDL_INCLUDE_DIR "C:/Users/Joseph/Programming/Github/Libraries/SDL2_mixer- 2.0.0/include" CACHE PATH "")
set(SDL_MIXER_LIBRARY "C:/Users/Joseph/Programming/Github/Libraries/SDL2_mixer-2.0.0/lib/x86/SDL2_mixer.lib" CACHE FILEPATH "")

All the paths are still valid.

And here's the command I'm using: cmake -C "C:/Users/Joseph/Desktop/initial_cache.cmake" --build "C:/Users/Joseph/Programming/Github/CorsixTH/build" -g "Visual Studio 12 2013" C:/Users/Joseph/Programming/Github/CorsixTH/

The command terminal's output:

loading initial cache file c:/Users/Joseph/Desktop/initial_cache.cmake
-- Building for: Visual Studio 12 2013
Note: SDL audio is enabled (default)
Note: FFMPEG video is enabled (default)
Note: FreeType2 is enabled (default)
Note: Visual Leak Detector is disabled (default)

Building CorsixTH
-- Could NOT find SDL (missing:  SDL_INCLUDE_DIR)
CMake Error at CorsixTH/CMakeLists.txt:105 (message):
Error: SDL library not found, it is required to build.  Make sure the path
  is correctly defined or set the environment variable SDLDIR to the correct
  location

-- Configuring incomplete, errors occurred!
See also "C:/Users/Joseph/CMakeFiles/CMakeOutput.log".

After the first successful use of this cache file I added more commands and then it stopped working so I removed the new commands but this didn't make it work again.

I've tried deleting the cmake cache by telling the CMake GUI to delete it and I've tried using a fresh download of the CorsixTH source code directory.

If I look at CrosixTH/CMakeLists.txt and CMake's Modules\FindSDL.cmake the SDLDIR environment variable really has to be there (it is not cached and therefore read every time the configuration process starts again).

So I assume that what happened was the moment you changed something in your CMakeLists.txt you re-triggered ZERO_CHECK and your VS environment is missing the SDLDIR variable.

You you chould either:

Add it to your global environment variables
Add it to your VS project's environment variables (not yet possible with CMake itself)
Add set(ENV{SDLDIR} "C:/Users/Joseph/Programming/Github/Libraries/SDL2-2.0.3") to your cache file (but that would be not comply with to put only cache variables in there)
Write your own VS toolchain file for this kind of presets (that's what I've done to get those kind of things working reliable)
