Hello,
I have a question regarding kdesrc-build and CMake.
I setup the build environment variables and ran kdesrc-build and got
a
compiler error kinfocenter.
I investigated
/home/gregor/kde/src/build/kde/workspace/kinfocenter/CMakeCache.txt
and
found the following lines
//The directory containing a CMake configuration file for
KF5Service.
KF5Service_DIR:PATH=/usr/lib64/cmake/KF5Service
//The directory containing a CMake configuration file for
KF5Solid.
KF5Solid_DIR:PATH=/usr/lib64/cmake/KF5Solid
//The directory containing a CMake configuration file for
KF5Wayland.
KF5Wayland_DIR:PATH=/usr/lib64/cmake/KF5Wayland
The directories of the needed KF5 frameworks point to the system
wide
installed ones.
I removed the system-wide devel package for solid (because it caused
the
compiler error) and ran kdesrc-build again:
//The directory containing a CMake configuration file for
KF5Service.
KF5Service_DIR:PATH=/usr/lib64/cmake/KF5Service
//The directory containing a CMake configuration file for
KF5Solid.
KF5Solid_DIR:PATH=/home/gregor/kde/usr/lib64/cmake/KF5Solid
//The directory containing a CMake configuration file for
KF5Wayland.
KF5Wayland_DIR:PATH=/usr/lib64/cmake/KF5Wayland
Now it shows the correct (local) path for solid (but not the other
ones).
Is
there an environment variable or something I have to set to tell
Cmake to
always look for local modules first?
Try CMAKE_PREFIX_PATH. See e.g. this old blog post on the matter:
https://blogs.kde.org/2008/12/12/how-get-cmake-find-what-you-want-it
Thanks for the hint. The variable was already set:
CMAKE_PREFIX_PATH=/home/gregor/kde/usr:
In the blog post, it is said, that CMAKE_PREFIX_PATH is searched
_first_. I
find it strange that I had to uninstall the system-wide devel package
in
order to have cmake pick up the library in /home/gregor/kde/usr. And
for the
other libraries it still uses /usr. Any idea how to investigate this
further?
If you have previously run CMake without setting CMAKE_PREFIX_PATH you
will need to remove your build directory first, otherwise it will
reuse modules it has already found.
Hello Ben, I already removed the build dir (forgot to mention that). I
assume that it should be sufficient to delete the build dir of the
application that should be configured
(/home/gregor/kde/src/build/kde/workspace/kinfocenter/) and not also
those of the imported libraries (KF5Service, KF5Solid, KF5Wayland etc.).
I wonder if there is maybe an additional (global) cmake cache or a
special behaviour of kdesrc-build.
