[CMake] Adding a header dependency on a generated header file. (was PRE_BUILD custom commands don't appear to be working....)

[Josef Karthauser]

So, I've created a new target to generate the header, and made the
library target depend upon it.  How do I now make sure that the
generated header is considered in the dependency checks for the objects
build from the CPP files that #include it?

But you should be able to put your custom command in its own custom
target and then use ADD_DEPENDENCIES to make the custom target build
*before* any build steps for the library...

 

Have you tried that?

ADD_CUSTOM_COMMAND: Add a custom build rule to the generated build
system.
....
Note that the PRE_BUILD option is only supported on Visual Studio 7 or
later. For all other generators PRE_BUILD will be treated as PRE_LINK. 
....


We have tried, and this is next to impossible to do with a makefile,
sorry...
