[gz-rendering7] new port

[talregev]

• Changes comply with the maintainer guide
• The name of the port matches an existing name for this component on https://repology.org/ if possible, and/or is strongly associated with that component on search engines.
• Optional dependencies are resolved in exactly one way. For example, if the component is built with CMake, all find_package calls are REQUIRED, are satisfied by vcpkg.json's declared dependencies, or disabled with CMAKE_DISABLE_FIND_PACKAGE_Xxx
• The versioning scheme in vcpkg.json matches what upstream says.
• The license declaration in vcpkg.json matches what upstream says.
• The installed as the "copyright" file matches what upstream says.
• The source code of the component installed comes from an authoritative source.
• The generated "usage text" is accurate. See adding-usage for context.
• The version database is fixed by rerunning ./vcpkg x-add-version --all and committing the result.
• Only one version is in the new port's versions file.
• Only one version is added to each modified port's versions file.

Usage test pass with following triplets:

x86-windows
x64-windows
x64-windows-static

[talregev]

it still works in progress

[dg0yt]

Do not merge.

• We need [gz-cmake3] Fix export of static deps #34667 first.
• The current state is invald w.r.t. to the versions registry.

@dg0yt I got an error on linux on this port. I will report it here when I can.

[talregev]

@dg0yt Can I ask your help?
When I compile this port for linux, when it find ogre2, it search also for terra:

CMake Error: install(EXPORT "gz-rendering7-ogre2" ...) includes target "gz-rendering7-ogre2" which requires target "terra" that is not in any export set.
CMake Error in ogre2/src/CMakeLists.txt:
  export called with target "gz-rendering7-ogre2" which requires target
  "terra" that is not in any export set.

I am not sure how to solve it. This error is not connected to your changes.
I am sharing here logs.

@jimwang118 @dg0yt @MonicaLiu0311
The ci skip the gz-rendering7 port because it depend on ogre2 port that skip by request in the ci.

[dg0yt]

you refer to ogre-next... yes, depending on it means having no CI. And not getting a new port.
I don't know the state of the ogre world. Maybe at least one triplet could be switched.

You need to export terra now.

I won't do anything before #34667 is merged. I look at one problem and find two more. This doesn't scale well...

I am waiting for your PR will merge.
meanwhile I got this problem and I check this before your fix and it also happen.
Also the terra target is created inside the gz-rendering7.
How I can export this target?

You should use the install command to export terra.

@jimwang118 @dg0yt

I added similar line as here:
https://github.com/gazebosim/gz-rendering/blob/gz-rendering7_7.4.1/ogre2/src/CMakeLists.txt#L63
install(TARGETS "terra" DESTINATION ${GZ_RENDERING_ENGINE_INSTALL_DIR})

And I still get the same error. What should I do?

[dg0yt]

CMake Error in ogre2/src/CMakeLists.txt:
 export called with target "gz-rendering7-ogre2" which requires target
 "terra" that is not in any export set.

You need install(TARGETS terrra EXPORT <export_set> ...).
Then install(EXPORT <export_set> ...) will be happy.

[talregev]

@dg0yt Thank you for your help.
I try:

install(TARGETS "terra" EXPORT terra)
install(EXPORT terra DESTINATION ${GZ_RENDERING_ENGINE_INSTALL_DIR})

And I got the same error.
I also try with different names for export_set.

[talregev]

@dg0yt I got it. Thank you for your help.
@jimwang118 ready for review.

[talregev]

@jimwang118 It ready for review.
