Summary:                    '$' becomes '$$' in compile_commands.json
Description: 
If your compile command contains a '$' character, it'll be incorrectly emitted
as '$$' in compile_commands.json if CMAKE_EXPORT_COMPILE_COMMANDS is enabled.

Steps to Reproduce: 
1) extract example.zip
2) cd example && cmake -DCMAKE_EXPORT_COMPILE_COMMANDS=True .
3) make VERBOSE=1
4) see that the compile command is

/usr/bin/cc  -DFOO="\"\$\""   -o CMakeFiles/foo.dir/foo.c.o   -c
/tmp/cmake/foo.c

5) open up compile_commands.json
6) see

"command": "/usr/bin/cc  -DFOO=\"\\\"\\$$\\\"\"    -o CMakeFiles/foo.dir/foo.c.o
  -c /tmp/cmake/foo.c"

which is wrong, since it should be $ instead of $$.
