[boost-test] unable to find using cmake, but vcpkg installed it

[ofloveandhate]

Describe the bug

I'm using vcpkg in CMake on Windows in Visual Studio Code (to build a C++/Python library using Boost.Python). In my vcpkg.json I have

{
    "dependencies": [
        {
            "name": "python3",
            "features": ["extensions"]
        },
        "gmp",
        "mpfr",
        "mpc",
        "boost-log",
        "boost-multiprecision",
        "boost-serialization",
        "boost-test",
        "boost-filesystem",
        "boost-python",
        "eigen3"

    ]
}

Running the CMake: Configure project successfully installs my requirements, telling me (excerpted to focus on boost-test):

[cmake] The package boost-test is compatible with built-in CMake targets of FindBoost.cmake:
[cmake] 
[cmake]     find_package(Boost REQUIRED COMPONENTS test)
[cmake]     target_link_libraries(main PRIVATE Boost::test)
[cmake] 
[cmake] or the generated cmake configs via:
[cmake] 
[cmake]     find_package(boost_test REQUIRED CONFIG)
[cmake]     target_link_libraries(main PRIVATE Boost::test)

and then in CMake, I do find_package to find the things I requested from vcpkg, using either of the forms suggested. It finds my other requirements, but I can't get it to find boost-test, using either of the recommended lines, and I get the error:

[cmake] CMake Error at C:/Users/amethyst/repo/vcpkg/scripts/buildsystems/vcpkg.cmake:859 (_find_package):
[cmake]   Could not find a package configuration file provided by "boost_test"
[cmake]   (requested version 1.87.0) with any of the following names:

[cmake]     boost_test-config.cmake

[cmake]   Add the installation prefix of "boost_test" to CMAKE_PREFIX_PATH or set
[cmake]   "boost_test_DIR" to a directory containing one of the above files.  If
[cmake]   "boost_test" provides a separate development package or SDK, be sure it has
[cmake]   been installed.

Looking in the directory where the other .cmake files are for boost components, I see none for boost_test. BUT, I do see one for boost_unit_test_framework, which is what I was kinda expecting since I am adapting my project from MacOS/Linux to Windows, and previously was looking for boost_unit_test_framework.

So, I suspect that the output from vcpkg telling me how to find boost-test are incorrect.

Indeed, I can find by using

find_package(Boost REQUIRED COMPONENTS unit_test_framework)

which is how I was finding it before.

Environment

• OS: Windows
• Compiler: revision

To Reproduce
Steps to reproduce the behavior:

1. CMake Configure for a project in Visual Studio
2. ask for "boost-test", in vcpkg.json
3. use a vcpkg recommended cmake line to try to find boost-test: either find_package(Boost REQUIRED COMPONENTS test) or find_package(boost_test REQUIRED CONFIG) to try to find
4. Run CMake Configure
5. Error

Expected behavior
If I find boost-test from vcpkg, the way it tells me to find that package in cmake should match and be usable.

Confirmed, I can repro this issue.
