The other day, some user of Extra CMake Modules (A collection of utilities and find modules created by KDE), asked if there was an easy way to query cmake for wherever the KDEInstallDirs points to (KDEInstallDirs is a set of default paths that mostly is good for your system, iirc based upon GNUInstallDirs but with some extensions for various Qt, KDE and XDG common paths, as well as some cross platform additions). I couldn’t find an easy way of doing it without writing a couple of lines of CMake code.
Getting the KDE_INSTALL_(full_)APPDIR with default options is:
|
1 2 |
$ cmake -DTYPE=APPDIR .. KDE_INSTALL_FULL_APPDIR:/usr/local/share/applications |
and various other options can be set as well.
|
1 2 |
$ cmake -DCMAKE_INSTALL_PREFIX=/opt/mystuff -DTYPE=BINDIR .. KDE_INSTALL_FULL_BINDIR: /opt/mystuff/bin |
This is kind of simple, but let’s just share it with the world:
|
1 2 3 4 5 6 7 |
cmake_minimum_required(VERSION 3.0) find_package(ECM REQUIRED) set (CMAKE_MODULE_PATH ${ECM_MODULE_PATH}) include(KDEInstallDirs) message("KDE_INSTALL_FULL_${TYPE}: " ${KDE_INSTALL_FULL_${TYPE}}) |
I don’t think it is complex enough to claim any sorts of copyrights, but if you insist, you can use it under one of the following licenses: CC0, Public Domain (if that’s in your juristiction), MIT/X11, WTFPL (any version), 3-clause BSD, GPL (any version), LGPL (any version) and .. erm. whatever.
I was trying to get it to work as a cmake -P script, but some of the find_package calls requires working CMakeCache. Comments welcome.
