Please check also the cmake wiki and FAQ.
There are also many examples in vtk, itk and KDE 4 svn 
( http://websvn.kde.org/trunk/KDE/ )

See the flags below.
You can also check
if (MSVC)
and
if (CMAKE_COMPILER_IS_GNUCXX)
to test for the compiler in cmake.

You can set CMAKE_BUILD_TYPE e.g. to DEBUG or RELEASE, and then the specific compile flags will be used:

set(CMAKE_CXX_FLAGS_RELEASE "-O2")
set(CMAKE_CXX_FLAGS_DEBUG "-g -O2 -fno-reorder-blocks -fno-schedule-insns 
-fno-inline")
set(CMAKE_C_FLAGS_RELEASE    "-O2")
set(CMAKE_C_FLAGS_DEBUG      "-g -O2 -fno-reorder-blocks -fno-schedule-insns 
-fno-inline")

Bye
Alex
