Provide PackageConfig module for CMake

[breznak]

so nupic.core libraries can be easily detected & included by 3rd party C++ programs.

Ok, an update, we probably shouldn't write our own FindXXX.cmake

Do not write find modules for packages that themselves build with CMake. Instead provide a CMake
package configuration file with the package itself. See our tutorials on CMake Packages.
But, instead just create a package config

https://cmake.org/Wiki/CMake/Tutorials/How_to_create_a_ProjectConfig.cmake_file

The desired result is:
We can call find_package(NupicCore) in an external cmake repo and use the includes/libraries/binaries/flags from this project.

@numenta/nupic-committers Haven't we tried this before?

Not exactly. I think @breznak is suggesting we provide a generic CMake module so that consumers of nupic.core can integrate it easily into their own CMake builds. 👍 from me.

[scottpurdy]

👍 from me as well

Bump. Is anyone linking their 3rd party (cmake based) app to nupic.core?

Thanks for the update. No one is currently planning on working on this at the moment.
