Hi Hiba
Firstly, the meaning of "target_include_dirs-NOTFOUND" is that CMake
tried to read a target property into the variable
'target_include_dirs', but the property was missing. So CMake set the
'target_include_dirs' variable to the string
"target_include_dirs-NOTFOUND". Same has happened with the
"target_link_libraries-NOTFOUND" error -- it means CMake tried to read
a property into the 'target_link_libraries' variable, but the property
wasn't set.
Where this actually happens is here:
https://git.gnome.org/browse/gtk-doc/tree/cmake/GtkDocConfig.cmake.in?id=64d940b45474c4e98c4ed9bb035248a40145527d#n319
and here:
https://git.gnome.org/browse/gtk-doc/tree/cmake/GtkDocConfig.cmake.in?id=64d940b45474c4e98c4ed9bb035248a40145527d#n336
It could well be that the code is just broken if the library for your
project doesn't link against any other libraries. I'll look into that.
However, looking at libraqm it seems to link against 3 libs (Freetype,
Harfbuzz and Fribidi).
Are you calling target_link_libraries() and target_include_dirs() at
all for the library you're documenting? If not, that explains why this
problem is occuring, but I think that things will break further down
because the gtkdoc-scanobj tool needs to actually compile and run a
program linked against your library, and so it needs to know all of
the dependencies.
If you can share your current CMakelists files for the library I can
try and reproduce the issue myself. I don't think the
GtkDocConfig.cmake module is widely used yet so it's quite likely that
you've found some kind of bug.
