Cmake fails with in-tree build even when in a different directory

I'm trying to build SDL2 for Linux Mint 15. It requires Cmake, but when I try to run cmake, it gives me this error:

Code:

Prevented in-tree built.  Please create a build directory outside of the SDL source code and call cmake from there

I get this message even when trying to build from an empty directory elsewhere in the file system. I've tried using a new build directory in the SDL2 directory, and in a new directory one level up from the SDL2 directory.

I read that on Windows systems, this can be caused by an out of date MingW version, so I checked the versions on gcc and cmake. They both seem to be current. I checked those because I *think* gcc is sort of the Linux versions of MingW.

Can someone help me figure out what I'm missing?

System:
HP 2000-416dx
AMD E-300 APU
Linux Mint 15 "Olivia" 64 bit
gcc version 4.7.3
cmake version 2.8.10.1

It's your c compiler
MinGW, a contraction of "Minimalist GNU for Windows"

From the man page for Cmake

Quote:

USAGE
cmake [options] <path-to-source>
cmake [options] <path-to-existing-build>
DESCRIPTION
The "cmake" executable is the CMake command-line interface. It may be used to configure projects in scripts. Project configuration settings may be specified on the command line with the -D option. The -i option will cause cmake to interactively prompt for such settings.

Read the man page, if you have questions, make a list and post back.
