In CMake, you specify targets to build. CMake doesn't like it when
different targets have the same name. Both libgnucap.so and the gnucap
executable would have the same target name (CMake prepends "lib" to
libraries on most platforms). My workaround is to build the main
executable as "gnucap-ui" but then install it back as "gnucap".

I wasn't aware that GnuCap installed header files. I should probably
figure out how the build process is supposed to work before I write one.

Should the libraries be install in lib, or elsewhere, then?

$ cmake -DCMAKE_INSTALL_PREFIX:PATH=/my/little/place ..
$ make

Alternatively, you can edit this (and other settings) in a text user
interface by running:

$ ccmake ..

Be sure to configure, and then generate before exiting. If you wanted,
you could also run:

$ cmake-gui ..
