[CMake] Automatic dependency scanner of CMake 2.4.7

[Juan Sanchez]

According to the FAQ:
http://www.cmake.org/Wiki/CMake_FAQ#CMake_dependency_scanner

"#if 0" shouldn't work either.

How was the programming bad?  Both /* */ comments and conditional
statements are handled equally well by the c pre processor.

Since each C/C++ compiler has a cpp, wouldn't it be good to adopt the
dependency scanner to use cpp underneath?

Thanks,

Juan
