Howto include private headers

[PS76]

I want to include private headers from a Qt module. Therefore the following lines are added to the module's .pro file:

PRIVATE_HEADERS += \
    declarativechart_p.h

But after running "make" the private headers are not found. Are there other steps necessary for adding private headers?

You need to have QT += $${modulename}-private

There is no special processing for PRIVATE_HEADERS variable in qmake, i.e. it's just your local variable

The problem is that the private headers are not copied during building Qt from source: https://codereview.qt-project.org/218637

It seems like private headers need to be handled via sync.profile, not qmake
