When this property is set to true, the precompile header compiler options
|
|
|
|
|
will contain a compiler flag which should warn about invalid precompiled
|
|
|
|
|
headers e.g. ``-Winvalid-pch`` for GNU compiler.
|
|
|
|
|
|
|
|
|
|
This property is initialized by the value of the
|
|
|
|
|
:variable:`CMAKE_PCH_WARN_INVALID` variable if it is set when a target is
|
|
|
|
|
created. If that variable is not set, the property defaults to ``ON``.
