Add BDD utilities; use them for narrowing/propagation of linear equality constraints (#5192) 
* Add a few helper methods for encoding sets of integers as BDDs

* Use BDD functions in solver

* Add bdd::find_int

* Use bdd::find_int in solver

* Add narrowing for linear equality constraints

* Simplify code for linear propagation

* Add test for later

* Narrowing can only handle linear constraints with a single variable

* Need to push_cjust

clean up CMake code (#5182) 
* CMake: simplify FindGMP.cmake

Remove printing of all the different variables, and let FPHSA output the library
name. Add an imported target, which bundles the library and the include
directories for easier usage.

* fix build: vector::c_ptr() now is vector::data()

* CMake: use Threads::Threads imported module

Otherwise the setting of THREADS_PREFER_PTHREAD_FLAG has no effect.

* CMake: remove needless policy setting

The minimum required version is CMake 3.4, where these policies are already set
to new because they were introduced earlier.

* CMake: remove needless variable expansion
