Re: [CMake] Listing all the include directories

[Saad Khattak]

Thanks Robert. Too bad that this something I cannot inspect. A list of
include directories would be useful even with unexpanded generator
expressions.

CMake-server mode sounds like an interesting option.

Re: [CMake] Listing all the include directories

[Robert Maynard]

In general your options are to look at the command line or use
cmake-server mode to query the code model. The full set of include
directories is not known while configuring due to generator
expressions expanding after the configure step.

[CMake] Listing all the include directories

[Saad Khattak]

Hi,

I have many libraries and packages that are being linked using
target_link_libraries(...) where CMake takes care of the include
directories. There are cases where I get compile errors because I don't
know the exact include directories.

I thought perhaps I could get the include directories of my target by doing
the following:

get_target_property(INCLUDE_DIRS MyExeThatLinksToManyLibs
INCLUDE_DIRECTORIES)
message(STATUS ${INCLUDE_DIRS}) # hoped that this would print all the
include directories

Unfortunately, that did not work as expected. It was missing directories
that I know are added to the include directories of the target (because the
compiler is able to find the headers properly).

Apart from sifting through the compile commands, is there a nice way to
debug the include directories of a target?

Thank you,
Saad
