Hello,

I try to find a way to enable VS\_NO\_COMPILE\_BATCHING property only for a specific build type.  
I have `set_property(TARGET test_target PROPERTY VS_NO_COMPILE_BATCHING ON`  
And I try to do something like this :  
`set_property(TARGET test_target PROPERTY $<$<CONFIG:Coverage>:VS_NO_COMPILE_BATCHING ON> )`  
or  
`set_property(TARGET test_target PROPERTY $<$<CONFIG:Coverage>:VS_NO_COMPILE_BATCHING> $<$<CONFIG:Coverage>:ON> )`  
or  
`set_property(TARGET test_target PROPERTY "$<$<CONFIG:Coverage>:VS_NO_COMPILE_BATCHING ON>" )`  
or  
`set_property(TARGET test_target PROPERTY "$<$<CONFIG:Coverage>:VS_NO_COMPILE_BATCHING?ON>" )`

None of them activate the property.  
How can I disable MSVC compiler batching only for a specific config?

Thank you

Not all properties support generator expressions. However, even if they do, it is only the _value_ that supports them. You probably want something like this:

```cmake
set_property(TARGET blah
  PROPERTY
    VS_NO_COMPILE_BATCHING "$<IF:$<CONFIG:Coverage>:ON,OFF>")

```
