// 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
