Qt5和CMAKE_AUTORCC

Question

I am attempting to port an existing project using Qt to use cmake. The project has (a few) ui and (one) qrc files. In the CMakeLists.txt, if I use:

set(CMAKE_AUTOUIC ON)

and generate a Visual Studio (2015) project, it has a pre-build step, generating the sources from the ui files, and adding those generated files to the VS project. However, if I include the qrc file in the project sources, and then set:

set(CMAKE_AUTORCC ON)

The generated project no longer has the pre-build step. It does contain the corresponding qrc.cpp file. However, when the project build, it fails because the file doesn't exist, and doesn't get generated. I've also tried setting CMAKE_AUTORCC to OFF , and using QT5_ADD_RESOURCES . That doesn't remove the ui prebuild step, but doesn't add the qrc.cpp to the project.

I'm using Qt 5.6.0 and cmake 3.5.2.

I realize it's been almost 4 months, but I ran into the same exact problem just now, and read through your question. After looking through Qt doc on icons/qrc resource system, I have a working solution. I have all 3 settings in the same CMakeLists.txt file -- previously had the first two on:

set (CMAKE_AUTOMOC ON)
set (CMAKE_AUTOUIC ON)
set (CMAKE_AUTORCC ON)

Then when you add your exe/dll, do thus:

addlibrary (${myDLL} SHARED ${mySRC_LIST} ${myQRC_LIST})

where, you guessed it, the new list of files ${myQRC_LIST} contains the list of .qrc files. Voilà! My first try I had this result, which is very rare!

Of course I could have combined my .qrc files into ${mySRC_LIST} as well, but I like to keep my lists homogeneous. Whatever you do, please read through Qt Resource Doc so that the icons get included properly. Hope this helps.
