that’s added to KDE’s CI system’s build metadata. (This doesn’t affect you
locally, but perhaps if someone wants to use kdesrc-build with labplot or
move the project onto Jenkins eventually.)

Once I get labplot to build on OSX/CI I will commit these changes to KDE’s
build metadata repo.

OK, but it would be better, if CMake knew, that it could search for the libs
in the prefix specified via "-DCMAKE_PREFIX_PATH=/opt/local” like this:
---
$ git diff
diff --git a/CMakeLists.txt b/CMakeLists.txt
index 8f367e6..968c1a4 100644

        EXEC_PROGRAM (${GSL_CONFIG} ARGS "--version" OUTPUT_VARIABLE gsl_version)

Don’t know whether this is the preferred way to achieve what I intend to get.


Anyway, doing this I got much further, but then ran into this:
---

Is this due to the use of clang on my end?
