Subdirs template: dependencies on submodules custom targets

I would like to be able to call a custom target on my submodules from the subdirs template .pro file.

I have a subdirs .pro file:

TEMPLATE = subdirs

{{SUBDIRS = }}
{{  submodule1 }}

  submodule2

submodule1.subdir = sub/module1

submodule2.subdir = sub/module2

 

 It generates a Makefile like:

{{SUBTARGETS    =  }}

  sub-modules-submodule1{{}}

  sub-modules-submodule2{{}}

 sub-modules-submodule1-all: FORCE

   @test -d sub/module1 || mkdir -p sub/module1/

  cd sub/module1/ && ( test -e Makefile || $(QMAKE) -o Makefile path/to/sub/module1/module1.pro -spec linux-g++ CONFIG+=debug CONFIG+=qml_debug ) && $(MAKE) -f Makefile all

 

My submodules know a target I cannot invoke from the subdirs .pro file directory.

What I would like to write in the subdirs .pro file is something like:

submodule_target.depends = submodule1.target.submodule_target submodule2.target.submodule_target{{}}

So it can generate a Makefile with:

 

submodule_target: sub-modules-submodule1-submodule_target sub-modules-}}{{submodule2-submodule_target{{}}

 

sub-modules-submodule1-submodule_target:{{}}

  @test -d sub/module1 || mkdir -p sub/module1/

  cd sub/module1/ && ( test -e Makefile || $(QMAKE) -o Makefile path/to/sub/module1/module1.pro -spec linux-g++ CONFIG+=debug CONFIG+=qml_debug ) && $(MAKE) -f Makefile submodule_target

 

sub-modules-submodule2-submodule_target:{{}}

  @test -d sub/module2 || mkdir -p sub/module2/

  cd sub/module2/ && ( test -e Makefile || $(QMAKE) -o Makefile path/to/sub/module1/module2.pro -spec linux-g++ CONFIG+=debug CONFIG+=qml_debug ) && $(MAKE) -f Makefile submodule_target

 

So now I could invoke my subdirs .pro file with 'make }}{{submodule_target', like I can with the default targets (install, clean, all, ...){{}}

 

Maybe it's already feasible, but I couldn't find a way to do it.

 

Thanks.
