// 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
