[CMake] Eclipse tries to build x64 instead of x86

[John Drescher]

> Ok, nevermind, I built again using "-DCMAKE_BUILD_TYPE=Release" and that worked.  I wiped the build directory entirely and did "-DCMAKE_BUILD_TYPE=Release" and it's working again.  Strange.  Maybe some files just got screwed up somehow.  That seems to have fixed it so please disregard my previous question.

I have seen this once on a Visual Studio 2005 C++ project with CMake
2.8.0 and wiping the cache and regenerating the config also fixed the
issue.
