Ok then I need to remove the install directive for the headers in src.pro in case of qt_framework.
qwt.prf is for building your application after qwt has been installed. So my question was about what happens, when you have changed qwt.prf + built and installed everything and then you try to build your application with "CONFIG += qwt".
About building qwt: I thought you could build designer plugin and examples successfully when "CONFIG += lib_bundle" was added without any further changes ?
If not the local directory of the framework ( in the build directory ) needs to be added to QMAKE_FRAMEWORKPATH in the project files used for building qwt. Please try this.
