While investigating a different issue, a CMake warning was noticed in the
build output, complaining about a `sed` regexp in a build rule:

    
    
    00:02:26.836 CMake Warning (dev) at common/thrift/CMakeLists.txt:238 (add_custom_target):
    00:02:26.836   Syntax error in cmake code at
    00:02:26.836 
    00:02:26.836     /home/ubuntu/Impala/common/thrift/CMakeLists.txt:239
    00:02:26.836 
    00:02:26.836   when parsing string
    00:02:26.836 
    00:02:26.836     's|\(dispatchCallTemplated.*\));|\1) override;|'
    00:02:26.836 
    00:02:26.836   Invalid escape sequence \1
    00:02:26.836 
    00:02:26.836   Policy CMP0010 is not set: Bad variable reference syntax is an error.  Run
    00:02:26.836   "cmake --help-policy CMP0010" for policy details.  Use the cmake_policy
    00:02:26.836   command to set the policy and suppress this warning.
    00:02:26.836 This warning is for project developers.  Use -Wno-dev to suppress it.
    00:02:26.836 
    

This probably indicates an escaping problem: too many programs use the
backslash for escaping various special characters.
