[Cmake] LOAD_CACHE automatic exclude

[Andy Cedilnik]

Hi Julien,

Yes. Instead of using LOAD_CACHE, you use simple IMPORT.

So, here is what you do. In project A you configure file with the
following content:

SET(OPTION1 " at OPTION1 at ")
SET(OPTION2 " at OPTION2 at ")
...

Then you import this file in project B, and you are all set. Since all
the options are sets, you can overwrite them.

Look also chapter 6.7 in Mastering CMake.
