Review request for KDE Frameworks.


Repository: kcrash


Description
-------

Since KCrash is a framework that relies on DrKonqi binary being provided by a 3rd party software (kde-runtime), it should not make assumptions regarding location of the utility.

This patch makes KCrash to look for drkonqi binary first in $PATH, then falling back to CMAKE_INSTALL_PREFIX/LIBEXEC_INSTALL_DIR. With this patch it's possible for distributions to ship KDE Frameworks in normal prefix (/usr), but have current snapshots of kde-runtime in /opt/kde5 for instance.


Diffs
-----

  src/kcrash.cpp 87163cc 

Diff: https://git.reviewboard.kde.org/r/117016/diff/


Testing
-------

- Installed KCrash into /usr prefix
- Installed drkonqi from kde-runtime master to /opt/kde5 prefix
- started broken application
- no "could not find drkonqi" warning anymore
- crashed application, got drkonqi window


Thanks,

Dan Vrátil
