MultiNEAT is not automatically installed

[DaanZ]

We should supply the revolve CMakeLists.txt with

add_subdirectory(thirdparty/MultiNEAT)

But this does not build MultiNEAT successfully.

CMake Error at build/thirdparty/MultiNEAT/MultiNEATConfig.cmake:21 (include):
  include could not find load file:
/home/daanz/revolve_workspace/revolve_battery/build/thirdparty/MultiNEAT/MultiNEATTargets.cmake
Call Stack (most recent call first):
  cpprevolve/revolve/brains/CMakeLists.txt:21 (find_package)

The MultiNEAT cmake file should create the MultiNEATTargets.cmake, but this is not the case.

MultiNEAT is supposed to be installed system wise to make this work.
MultiNEATConfig.cmake is generated depending on your configuration.

This is the current situation, I understand that there is a better way to do this, without installing MultiNEAT and it would be preferrable, but I need more experience on cmake to understand how to do this properly.

I am going to read https://zhjwpku.com/assets/pdf/books/Managing.Projects.With.Gnu.Make.3Rd.Edition.pdf to possibly assist with this.

Not really. Make is an old tool very manual and unpractical. What I used as a reference in modern cmake is this: https://pabloariasal.github.io/2018/02/19/its-time-to-do-cmake-right/
