D7930: Kdevelop CMake plugin : use canonical paths to build.dir

[René J.V. Bertin]

rjvbb added a comment.


  To come back to the original subject, here's an example of an include statement that could easily go wrong when executed from a working directory that is not canonical but has a symlink in it that changes the directory level:
  
    /home/bertin/work/src/Scratch/KDE/KF5/kk-git/build/kdevplatform/sublime/examples/example2_autogen/EWIEGA46WW/moc_example2main.cpp:108: undefined reference to `Sublime::MainWindow::qt_metacall(QMetaObject::Call, int, void**)'
    CMakeFiles/example2.dir/example2_autogen/mocs_compilation.cpp.o: In function `~Example2Main':
    /home/bertin/work/src/Scratch/KDE/KF5/kk-git/build/kdevplatform/sublime/examples/example2_autogen/EWIEGA46WW/../../../../../../kdevplatform/sublime/examples/example2main.h:24: undefined reference to `Sublime::MainWindow::~MainWindow()'
  
  (Taken from an error message that's hopefully not relevant here)
