proper use of CMAKE_SOURCE_DIR

[mzimmers]

Hi all -

I'm trying to follow a Qt example on translations. In the video, the narrator adds this line to his CMakeLists.txt file:

qt_create_translation(QM_FILES $(CMAKE_SOURCE_DIR) simplequick.ts)

I've added an equivalent line to my file, and when trying to build, I get a rather strange-looking error:

ninja: error: 'C:/Users/Michael.Zimmers/Qt_projects/nga_demo/$(CMAKE_SOURCE_DIR)', needed by '.lupdate/latin.ts.stamp', missing and no known rule to make it

("latin.ts" is the name of my .ts file -- it's currently empty.)
I tried adding a definition for CMAKE_SOURCE_DIR in my project configuration, but that didn't change anything.

Any ideas what I'm doing wrong here? Thanks...

I am pretty sure the video is correct but you read it wrong. Cmake is using curly brackets for variables.

@Christian-Ehrlicher and I'm pretty sure you're right. (I think I need a vacation.) Thanks for catching that.

As long as we're on the general subject (sort of), later, he includes this line:

#install(FILES ${qm_files} DESTINATION ${INSTALL_EXAMPLEDIR})

I'm assuming that he defined INSTALL_EXAMPLEDIR but he doesn't explicitly mention it. Which Qt variable should I substitute for my project? (I'm using a conventional shadow build.)

Thanks...

I personally install qm files either in an 'translations' subdir or directly embed them in the resource file.

@Christian-Ehrlicher said in proper use of CMAKE_SOURCE_DIR:

Oh, I guess I misunderstood that line -- I thought he was referring to the build directory. But your answer implies that the install is actually within the source directory.

I think I'd like to use the first approach you mentioned. Should I create a variable for this directory within Creator, or is there something predefined for this purpose?

Thanks...
