Apologies for the wall of text.

Just to prove CMake wrong about OpenMP and ImageMagick, I then did this:

liam@...3128...:/home/inkrepo/experimental$ cd .. liam@...3128...:/home/inkrepo$ cat > openmp-test.cpp #include <omp.h> #include <stdio.h> int main() { #pragma omp parallel printf("Hello from thread %d, nthreads %d\n", omp_get_thread_num(), omp_get_num_threads()); }^D liam@...3128...:/home/inkrepo$ g++ -fopenmp openmp-test.cpp -o a.out liam@...3128...:/home/inkrepo$ ./a.out Hello from thread 3, nthreads 4 Hello from thread 0, nthreads 4 Hello from thread 2, nthreads 4 Hello from thread 1, nthreads 4 liam@...3128...:/home/inkrepo$ ls /usr/include/GraphicsMagick magick Magick++ Magick++.h wand liam@...3128...:/home/inkrepo$ ls /usr/include/magick analyze.h blob.h color_lookup.h common.h confirm_access.h deprecate.h enhance.h gem.h list.h magick.h monitor.h pixel_cache.h quantize.h resize.h statistics.h transform.h api.h cdl.h colormap.h compare.h constitute.h describe.h error.h gradient.h log.h magick_types.h montage.h pixel_iterator.h random.h resource.h symbols.h type.h attribute.h channel.h colorspace.h composite.h decorate.h draw.h forward.h hclut.h magic.h memory.h operator.h plasma.h registry.h shear.h texture.h utility.h average.h color.h command.h compress.h delegate.h effect.h fx.h image.h magick_config.h module.h paint.h profile.h render.h signature.h timer.h version.h

What I'm not getting here is why CMake requires libmagickcore-dev to be installed — on the same system, with the same installed packages, ./configure with no parameters passed says this:

Use gnome-vfs: yes Use openoffice files: yes Use relocation support: no Enable LittleCms: yes Enable DBUS: no Enable Poppler-Cairo: yes ImageMagick Magick++: yes Libwpg: yes Libvisio: yes Libcdr: no Doing Local Install: no

After installing libmagickcore-dev, I ran CMake again and it "worked". I then ran make -k (and got the expected errors with poppler), but then this error about missing Magick.h.

[ 20%] Building CXX object src/CMakeFiles/inkscape.dir/extension/internal/bitmap/blur.cpp.o /home/inkrepo/experimental/src/extension/internal/bitmap/blur.cpp:13:10: fatal error: 'Magick++.h' file not found #include <Magick++.h> ^ 1 error generated.

*TL;DR *how do we get CMake to properly recognize OpenMP support, recognize the correct Magick, and supply the correct headers?
