Get QtPlatformHeaders include path with Cmake

glennr

I am wanting to use a class from QtPlatformHeaders:

#include <QtPlatformHeaders/QCocoaNativeContext>

and I need to do this from CMake.

How do I get CMake to include the right path in the generated build files so that the above #include will work?

I'm including the main Qt5 packages is like this:

find_package(Qt5 COMPONENTS Widgets Gui REQUIRED)

It will work the way you did it according to the docs.

Except it doesn't, hence the question.

I need to somehow tell CMake how to set the proper include path. The relevant documentation is here https://doc.qt.io/qt-5/cmake-manual.html but it doesn't specifically say how to set the include path for QtPlatformHeaders.

Solved it like this:

execute_process(
    COMMAND qmake -query QT_INSTALL_HEADERS
    OUTPUT_VARIABLE Qt5_INCLUDE_DIR
    )

include_directories(${Qt5_INCLUDE_DIR})
