Failure to link interp2dtest to MacPorts gsl

[bkraessig]

The cmake installation of interp2d on my Mac completed only partially. The static library was built successfully, but the linking of the interp2dtest failed:

[ 71%] Built target interp2d_static
[ 85%] Linking C executable interp2dtest
ld: library not found for -lgsl
collect2: error: ld returned 1 exit status
make[2]: *** [interp2dtest] Error 1
make[1]: *** [CMakeFiles/interp2dtest.dir/all] Error 2
make: *** [all] Error 2

The CMakeCache.txt contains all the necessary entries for gsl:

GSL_CFLAGS:INTERNAL=-I/opt/local/include
GSL_FOUND:INTERNAL=1
GSL_INCLUDEDIR:INTERNAL=/opt/local/include
GSL_INCLUDE_DIRS:INTERNAL=/opt/local/include
GSL_LDFLAGS:INTERNAL=-L/opt/local/lib;-lgsl;-lgslcblas;-lm
GSL_LIBDIR:INTERNAL=/opt/local/lib
GSL_LIBRARIES:INTERNAL=gsl;gslcblas;m
GSL_LIBRARY_DIRS:INTERNAL=/opt/local/lib

I wonder whether this info didn't trickle down into the link command for interp2dtest.

Yep, it took a little while to track down what needed to be done, but I'd omitted the command to add the directory to the linker search path. It works for me now. Check out commit 59e8038 and let me know whether it fixes the issue for you too.
