Update README.md

The following libraries are also required by `scord`, but will be downloaded

and compiled by the project as part of the standard build process.

- [{fmt}]() version 8.0.1 or later.

- [spdlog]() version 1.9.2 or later.

- [{fmt}](https://fmt.dev/latest/index.html) version 8.0.1 or later.

- [spdlog](https://github.com/gabime/spdlog) version 1.9.2 or later.

- [Catch2](https://github.com/catchorg/Catch2) version 3.0.1 or later.

> **ℹ️** **Important**  

Margo and Argobots use `pkg-config` to ensure they compile and link correctly

  communicate with the service. The value provided here will be used to set

  the `bind_port` configuration option in the `${PREFIX}/etc/scord.conf`

  installed alongside the service.

- `SCORD_BUILD_EXAMPLES`: This option instructs CMakes to build the programs

- `SCORD_BUILD_EXAMPLES`: This option instructs CMake to build the programs

  contained in the `examples` subdirectory.

- `SCORD_BUILD_TESTS`: This option instructs CMake to build the tests

  contained in the `tests` subdirectory.

Thus, let's assume that we want to build `scord` with the following

configuration:

cmake -DCMAKE_PREFIX_PATH:STRING=/opt \

      -DCMAKE_INSTALL_PREFIX:STRING=/usr/local \

      -DSCORD_BUILD_EXAMPLES:BOOL=ON \

      -DSCORD_BUILD_TESTS:BOOL=ON \

      -DSCORD_TRANSPORT_LIBRARY=libfabric \

      -DSCORD_TRANSPORT_PROTOCOL=ofi+tcp \

      -DSCORD_BIND_ADDRESS=192.168.0.111 \

make

```

## Running tests

Tests are integrated in [CTest](https://cmake.org/cmake/help/book/mastering-cmake/chapter/Testing%20With%20CMake%20and%20CTest.html), CMake's testing facility. Once built, the

tests can be run in parallel using the `ctest` command line tool:

```console

~/projects/scord/build $ ctest --parallel 4

Test project /home/amiranda/var/projects/scord/repo/build

    Start 1: Scenario: Error messages can be printed

1/1 Test #1: Scenario: Error messages can be printed ...   Passed    0.14 sec

100% tests passed, 0 tests failed out of 1

Total Test time (real) =   0.14 sec

```

## Installing

Assuming that the CMAKE_INSTALL_PREFIX has been set (see previous step) and
