physx: add components

[SpaceIm]

Specify library name and version: physx/all

• I've read the guidelines for contributing.
• I've followed the PEP8 style guides for Python code in the recipes.
• I've used the latest Conan client version.
• I've tried at least one configuration locally with the
  conan-center hook activated.

Currenrly, PhysX doesn't export its targets, but it should be fixed by NVIDIAGameWorks/PhysX#222

PhysX has a target PhysX::PhysX which doesn't depend on all components. With current behaviour of conan, there is no way to properly model this target, since it is reserved for "custom conan global target".
Therefore, consumers could only link PhysX::PhysX with conan generators, without link errors, while they may have link errors without conan (if they use components not dragged by PhysX::PhysX, like PhysXExtensions, PhysXVehicle, PhysXCooking and PhysXCharacterKinematic, and forget to also link them).

It is possible to have a target PhysX::PhysX that doesn't contain all the components. If you have a look to the generated FindXXX.cmake file there is if to check if a target with a global name has already being generated, only if it isn't Conan will create the global one. So something like this works:

def package_info(self):
    self.components["PhysX"].names["cmake_find_package"] = "PhysX"
    self.components["PhysX"].libs = ["only-liba"]

    self.components["ALL"].names["cmake_find_package"] = "all-dependencies"
    self.components["ALL"].requires = ["PhysX"]

will create a target PhysX::PhysX with only the library only-liba and a target PhysX::all-dependencies with all of them.

Nice, updated.

CI stuck?

[conan-center-bot]

An unexpected error happened and has been reported. Help is on its way! 🏇

Now it is running, even though Github doesn't show it
