The argument to -include is a file which will be included, right ?
(Instead of having multiple identical "#include" lines within the source
code.)

You could do it using ADD_DEFINITIONS(-include ...)
but I would suggest you actually include that file everywhere (using -include
*might* make the cmake dependency scanning miss some dependencies)

Thanks, Alex !
Two questions, and an idea:
1. Why it could harm the dependency checking - because when including a
file this way it is not checked by the CMake dependency scanner ?
2. I found that MSVC 2003 & 2005 has similar option called "forced
include" (its switch-syntax is /FI <filename>). I also saw that it
appears in CMake's sources:
Source/cmLocalVisualStudio7Generator.cxx:353: {"ForcedIncludeFiles",
"FI", "Forced include files", "",
The real *pain* here is compatibility. I think the best solution will be
to write a module that adds forced includes (either "-include" for GCC
or "/FI" for MSVC) and maybe also check their dependencies. Please tell
me what you think.
Thanks,
Yinon
