I came to different solution. I have to build statically with some libraries
(including boost), and I use following approach to force CMake
build with static libs.

The question to other gurus: is it moral/correct to use CMake this way? :)

# Macro file
macro(MACRO_PUSH_VARIABLES)
	if(NOT DEFINED _PUSH_VERIABLES_COUNTER)
		set(_PUSH_VERIABLES_COUNTER 0)
	endif(NOT DEFINED _PUSH_VERIABLES_COUNTER)

	math(EXPR _PUSH_VERIABLES_COUNTER "${_PUSH_VERIABLES_COUNTER}+1")

	foreach(_CURRENT_VAR ${ARGN})
		set(_PUSH_VARIABLES_SAVE_${_CURRENT_VAR}_${_PUSH_REQUIRED_VARS_COUNTER} ${${_CURRENT_VAR}})
	endforeach(_CURRENT_VAR)
endmacro(MACRO_PUSH_VARIABLES)

macro(MACRO_POP_VARIABLES)
# don't pop more than we pushed
	if("${_PUSH_VERIABLES_COUNTER}" GREATER "0")
		foreach(_CURRENT_VAR ${ARGN})
			set(${_CURRENT_VAR} ${_PUSH_VARIABLES_SAVE_${_CURRENT_VAR}_${_PUSH_REQUIRED_VARS_COUNTER}})
		endforeach(_CURRENT_VAR)

		math(EXPR _PUSH_VERIABLES_COUNTER "${_PUSH_VERIABLES_COUNTER}-1")
	endif("${_PUSH_VERIABLES_COUNTER}" GREATER "0")
endmacro(MACRO_POP_VARIABLES)
