[CMake] Escaping $

[Kedzierski, Artur CIV NAVSURFWARCENDIV CORONA]

	Hi,

	I am trying to create FooConfig.cmake by having
FooConfig.cmake.in and running CONFIGURE_FILE(FooConfig.cmake.in
FooConfig.cmake)
on it.
	In FooConfig.cmake.in, I have something like:
SET(MY_LOCAL ${CMAKE_INSTALL_PREFIX}/include/foo)
IF (WIN32)
	SET(MY_LOCAL \$(MY_LOCAL) ${CMAKE_INSTALL_PREFIX}/include/foo_win32)
ENDIF (WIN32)
SET(Foo_INCLUDE_DIR \$(MY_LOCAL)

	My goal is to have this generated:
SET(MY_LOCAL /usr/include/foo)
IF (WIN32)
	SET(MY_LOCAL $(MY_LOCAL) /usr/include/foo_win32)
ENDIF (WIN32)
SET(Foo_INCLUDE_DIR $(MY_LOCAL)

	In other words, I want to escape dollar sign for $(MY_LOCAL) so
that it doesn't get evaluated during creation of FooConfig.cmake. How
do I do that? "\$" leaves it as it is and $$ doesn't work either. 
	Is there any other way of escape the dollar sign?
	Thank You.
