[CMake] how to escape the $ dollar sign?

[Christopher Lang]

Hi,

I am trying desperately to get the dollar sign ($) escaped properly in the 
following:

ADD_CUSTOM_TARGET (read_potfiles_in ALL
	COMMAND grep -Ev '^\#|^\\[|^$' POTFILES.in > POTFILES.in.cmake
	WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR}
)                    

I searched everything but did not find a solution to get that dollar sign 
escaped.

The result always looks like this:

...
cd /home/chris/workspace/l2nl/po && grep -Ev '^#|^\[|^ POTFILES.in > 
POTFILES.in.cmake

Escaping with signle or double \\ does not work.

any help is much appreciated!

Chris
