Hi,

Without diving too deeply into it for lack of time at the moment, I suspect
it's because of the stuff around /CMakeLists.txt:721 -- if I recall
correctly, find_package(Coin3D...) will do two things:

* Search for Coin3D.pc (in this case, in /usr/local/libdata/pkgconfig) to
aide in configuring it properly
* Set COIN3D_* variables, also based on this name

However, FreeCAD is expecting it to be Coin3D, where graphics/Coin gives us
Coin. As a first step, I would attempt a replacement on all CMakeLists.txt
in this project to replace COIN3D_ with COIN_, and then replace the
find_package Coin3D with Coin, see if that solves it.
