freetype2 path mistakes if Anaconda is installed

[ioncodes]

If Anaconda is installed on your system, CMake will use the freetype2.lib from Anaconda, which is not able to compile in that case, because external symbols wont be found.

This applies to all Windows versions which are Anaconda compatible and to all aseprite versions.

However, this is not a bug of aseprite, but it might be useful for others to know!
