Passing variables to subprojects

[Ermoghen]

Hello, everyone!

I have the following situation:

ParentProject_1.pro
TEMPLATE = subdirs
INCLUDE_SUBSUBPROJECT = 1
SUBDIRS += Child.pro

ParentProject_2.pro
TEMPLATE = subdirs
INCLUDE_SUBSUBPROJECT = 0
SUBDIRS += Child.pro

Child.pro
TEMPLATE = subdirs
contains(INCLUDE_SUBSUBPROJECT, 1){
SUBDIRS += Subsubproject.pro
}

This does not work as is because the INCLUDE_SUBSUBPROJECT value is not transfered from parent projects to Child.pro, so Subsubproject.pro will never be included. One way seems to be using command line params for qmake, but it becomes problematic with more complex scenarios and I would really like to avoid it. Is there another way?

I would approach this with a Child.pri file that contains the common parts and two Child .pro files

Child.pro

include(Child.pri)

include(Child.pri)

To copy to clipboard, switch view to plain text mode 

ChildWithSubSub.pro

include(Child.pri)
 
# SubSub stuff

include(Child.pri)

# SubSub stuff

To copy to clipboard, switch view to plain text mode 

ParentProject1.pro

SUBDIRS +=ChildWithSubSub.pro

SUBDIRS +=ChildWithSubSub.pro

To copy to clipboard, switch view to plain text mode 

ParentProject2.pro

SUBDIRS +=Child.pro

SUBDIRS +=Child.pro

To copy to clipboard, switch view to plain text mode 

Cheers,

Thank you for your answer. Unfortunately, I have a more complex situation, in the sense that Child.pro has multiple subsubprojects that are combined differently when called from diffrent parents. Of course, your aproach remains valid and I will most probably use it. However, I was hoping to be able to have an unique Child.pro, becuase it seemed more ellegant to me.

Hmm.
Maybe try adding to the CONFIG variable?

I changed the approach and used something like you said in the first reply. Thank you!
