[CMake] Custom Build Type GCC on Linux

[Clemens Arth]

Hi,

I got a rather simple question. To add some special optimization flags 
to a custom build for one of our projects, I followed the guide to add a 
custom build type to my project using the example found here:

http://www.cmake.org/Wiki/CMake_FAQ#How_can_I_extend_the_build_modes_with_a_custom_made_one_.3F

I simply copy-pasted the code found there into a separate file and did 
the following:

project(Dummy)
include(maintainermode.cmake)
add_library(dummylib dummy.cpp)

To build it I run:
 >>cmake -DCMAKE_BUILD_TYPE=Maintainer ..
and
 >>make

Although everything seems to be correct, I can't get the stuff compiled 
with the new mode - it definitely adds the configuration, but I simply 
cannot build it like Release or Debug. It always sticks back to Debug.

Did I miss something here?
Regards
