How to know the compiler arguments set by include_directories,

CMAKE_<LANG>_FLAGS (with and whitout the uppercase build_type suffix)
doesn't contain anything that was set by the cmake commands mentioned
above.
I guess that the lack of response indicates that there is no way to do
that. Why so basic feature is missing? Something with the internals of
cmake that makes it hard to implement?
Well, your question isn't very clear. Are you interested in the
compiler flag (i.e. -I or -D) or would you like to query the active
include directories and definitions?
I'm interested on the literal parameters as they are passed to the
compiler.
The former are available through the variables CMAKE_INCLUDE_FLAG_C
and CMAKE_<lang>_DEFINE_FLAG, although AFAIK the latter may not be set
and defaults to -D.
The latter are available through the directory properties
INCLUDE_DIRECTORIES and DEFINITIONS. But doing some RTFM would have
told you that...
Yes, I RTFM. My test code contained a typo on the variable's name :-(
This remembers me why, being a bad typist, I try to avoid so much the
languages that accept undefined variables.
You can also set this:
set( CMAKE_VERBOSE_MAKEFILE on )
...that way you can see each command line invocation of the compiler and linker,
so you can check what's being passed.

or you can add "VERBOSE=1" right after the make command instead, for
on-the-fly testing.
