Consider making build of tests/examples explicit

[niclar]

Tying to build an example. -The cmake installation target for morph seem to miss e.g. Visual.h, ScatterVisual.h

This might have happened if you built and installed morphologica without first having installed the glfw library on your system. If the cmake process fails to find glfw, then a make install won't install Visual.h and all the other headers required for graphical programs. Here's the relevant section of the CMakeLists.txt: https://github.com/ABRG-Models/morphologica/blob/main/morph/CMakeLists.txt#L16

I'm just trying to build standalone_examples/schnakenberg with an installed morphologica (installed into /usr/local/). There are one or two headers that are not installed - base64.h is one.

[sebjameswml]

I made sure that the Schnakenberg example in standalone_examples/ will compile against an installed morphologica now (see the most recent couple of commits). Let me know which example you're trying to build if you are still stuck.

@sebjameswml Yeah I tried building/installing morph in isolation omitting examples & tests.

-Can you maybe make dependencies and examples explicitly optional (from the top level cmake) or the morph cmake "standalone". I.e use FindModule for glfw there

(also tried HEAD / 3efe3abf3f7003a8e82775138ee44a80deebfc42)

Making deps and examples explicitly optional is possible, so that it's a simple make && make install process (buildling all the tests and examples does take quite a while).

[sebjameswml]

I don't think I'll change the build process. When you type make, you'll just get all the tests and examples compiled.
