Hi,
at the moment each out of tree module has it’s one cmake/Modules path,
containing some cmake macros, mainly copied from some gnuradio source
tree.
As gnuradio development proceeds, cmake modules may be updated. It’s not
always necessary but perhaps good practice to keep the out of tree cmake
modules in sync.
As the number of oot- modules raises that means a lot of work.
As each oot module needs a gnuradio installation , why not to install
the complete cmake path together with gnuradio and reference these
modules in the oot CMakeLists.txt. As far as I can see only only two
lines in the main CMakeLists.txt file are effected.
The oot modules source would always use updated cmake files and if you
need macros not provided by gnuradio you can still keep them with your
module.

at the moment each out of tree module has it’s one cmake/Modules path,

GnuRadio already installs the required CMakefiles modules globally so
AFAIK, OOT modules are free to use them.
And it’s definitely a goal toward things are trending but there are
still some reason to keep local copies.
One reason OOT module would choose to keep a local copy is to be
compatible with older GR. For instance, in my OOT projects, I keep the
local FindGnuradio.cmake instead of using GrConfig.cmake because it
was broken until 3.7.2.1 …
For some other cmake modules, they’re not really “meant” to be used
outside of GR itself. Like the GrComponent.cmake . I know several
modules using it, but it’s been slightly modified to fit the
particular need of that OOT project because the default one is not
customizable enough (because not meant for anything by GR internal)
Cheers,
Sylvain

Also, usually to build an OOT-Module you shouldn’t need the whole GR
tree, but only the headers that had been used to build the
gnuradio-libraries as well as the libraries to link against.
So, when introducing another external dependency for OOT modules we
kind of make packaging harder. I don’t know if it’s worth the effort;
then, again, I’ve never built any gnuradio-devel (or the like) fedora
or debian/ubuntu package. It certainly would not hurt a development
machine badly to install the CMake modules.
Then, again, it would be preferable to have these modules installed
somewhere where CMake would automatically look for them, calling for a
package gnuradio-cmake-modules (or something of the like) on its own.
Greetings,
Marcus

Thinking about it, if we’re exchanging thoughts, I think the CMake
Modules would make a fine submodule in the GR main tree, as well as in
OOT modules.
But that would introduce to initializing and updating the cmake
submodule after cloning the gnuradio git repo; and that would make
installation more complicated. Maybe this could be fixed from within a
CMakeList, but then you need internet connectivity at first compile
time
