[CMake] CMake without C/C++ tests

[Дима]

So, I put the line
project (astl "NONE")
in CmakeLists.txt

But it does not work, i got these messages
$ cmake -DCMAKE_TOOLCHAIN_FILE=/home/Void/devel/svnroot/trunk/gcc/libstdc++-v3/astl/ToolchainFile.cmake /home/Void/devel/svnroot/trunk/gcc/libstdc++-v3/astl/
-- Configuring done
CMake Error: Cannot determine link language for target "astl".
CMake Error: CMake can not determine linker language for target:astl
-- Generating done
-- Build files have been written to: /home/Void/devel/svnroot/trunk/gcc/libstdc++-v3/astl
void at Impedance-Pad-T410:/home/Void/devel/build-astl$

Then i googled this http://www.cmake.org/pipermail/cmake/2006-July/010380.html
and add SET_TARGET_PROPERTIES(astl PROPERTIES LINKER_LANGUAGE CXX) to CMakeLists.txt
And got these
CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly.
Missing variable is:
CMAKE_CXX_CREATE_STATIC_LIBRARY


After it I add 
SET(CMAKE_CXX_CREATE_STATIC_LIBRARY "<CMAKE_CXX_COMPILER> -o <TARGET> <OBJECTS>")
in my CmakeLists.txt


And finally, after cmake command, i got these

void at Impedance-Pad-T410:/home/Void/devel/build-astl$ make
Scanning dependencies of target astl
Linking CXX static library libastl.a

make[1]: *** [CMakeFiles/astl.dir/all] Error 2
make: *** [all] Error 2
void at Impedance-Pad-T410:/home/Void/devel/build-astl$ 


Also, i can not compile project with standard gcc due to 
project (astl "NONE")


So, how can I remove -rdynamic option? Is it possible?
