    // a macro wrapping around try_compile or try_run that does not escape
    // semicolons in its parameters but just passes ${ARGV} or ${ARGN}.  In
    // this case a list argument like "-DVAR=a;b" gets split into multiple
    // cmake arguments "-DVAR=a" and "b".  Currently SetCacheArgs ignores
    // argument "b" and uses just "-DVAR=a", leading to a subtle bug in that
    // the try_compile or try_run does not get the proper value of VAR.  If we
    // call SetArgs here then it would treat "b" as the source directory and
    // cause an error such as "The source directory .../CMakeFiles/CMakeTmp/b
    // does not exist", thus breaking the try_compile or try_run completely.
    //
    // Strictly speaking the bug is in the wrapper macro because the CMake
    // language has always flattened nested lists and the macro should escape
    // the semicolons in its arguments before forwarding them.  However, this
    // bug is so subtle that projects typically work anyway, usually because
    // the value VAR=a is sufficient for the try_compile or try_run to get the
    // correct result.  Calling SetArgs here would break such projects that
    // previously built.  Instead we work around the issue by never reporting
