Solved Add subproject. How?
I've got on MacOS this issue on Qt Quick project that created from scratch:
How could I create new subproject? Is it bug related to this QTCREATORBUG-13975 or I am missing something?
The cause of troubles found :
TEMPLATE = subdirs
For defining projects with ability to add subprojects need to create first.
And inside of it add Qt Quick projects or whatever you want.
