[CMake] CheckIncludeFiles problem

[Micha Renner]

May be, there is an error when the compiler process the header file.
During CHECK_INCLUDE_FILES CMake invokes the Compiler to check whether
the header file works fines. In most cases reason is a missing
additional header files (but not always).

So, check the log files of CMake in the binary directory of your
project.

Greetings

Micha
