Bundle C++ app as a Yocto-ready ptest package

[Copilot]

Summary

Reviews and bundles the Area51 C++ project into a well-structured test package that can be used in Yocto Project builds via the ptest bbclass.

Changes

CMakeLists.txt

• Raised minimum CMake version to 3.10 and added C++11 standard requirement
• Replaced old variable-style Boost link (${Boost_UNIT_TEST_FRAMEWORK_LIBRARY}) with the modern imported target Boost::unit_test_framework
• Added GNUInstallDirs for standard, relocatable install paths
• Wrapped all test targets behind a BUILD_TESTING option (defaults ON)
• Added a proper ptest install target: all test binaries + run-ptest land in ${CMAKE_INSTALL_LIBDIR}/Area51/ptest/ (Yocto ${PTEST_PATH})
• Fixed broken install(FILES … TYPE BIN) syntax (was mixing FILES keyword with TYPE BIN)
• Named CTest tests descriptively (CatchTests, BoostTest_Factorial, …)

test2.cpp / test3.cpp

• Fixed duplicate BOOST_TEST_MODULE macro (test_module1 in all three Boost files). Now test_module1, test_module2, test_module3 respectively — required for correct Boost.Test linking.

run-ptest (new)

• Shell script consumed by Yocto's ptest-runner. Runs each test binary in sequence and emits PASS: / FAIL: lines in the format expected by the runner.

README.md

• Added project layout, dependency table, build/test/install instructions, and Yocto usage section.

meta-area51/recipes-test/area51/area51_git.bb (new)

BitBake recipe — see below.

Validation

All 4 CTest tests pass locally:

1/4 Test #1: CatchTests .......................   Passed    0.00 sec
2/4 Test #2: BoostTest_Factorial ..............   Passed    0.00 sec
3/4 Test #3: BoostTest_HumanFactorial .........   Passed    0.00 sec
4/4 Test #4: BoostTest_HumanName ..............   Passed    0.00 sec

100% tests passed, 0 tests failed out of 4

How to use in a Yocto build

1. Copy meta-area51/ into your bblayers.conf layer list (or add it as a separate layer).
2. Ensure ptest is in DISTRO_FEATURES (or EXTRA_IMAGE_FEATURES += "ptest-pkgs").
3. Add area51-ptest to your image recipe.
4. On the target, run:

   ptest-runner area51

Note: Before submitting to a production layer, add a LICENSE file to the repository and update LIC_FILES_CHKSUM with the real MD5 (md5sum LICENSE). Also pin SRCREV to a fixed commit SHA instead of ${AUTOREV} for reproducible builds.
