Refactor the library code used in the GenerateExportHeader test to use
an improved naming convention that more directly identifies what it
being tested, making use of namespaces to avoid possible symbol
collisions. This also eliminates duplicate cases such as `libshared()`
and `libshared_not_exported()` which had the same decoration, and adds
consistent pairings of <name>_EXPORT and <name>_DEPRECATED_EXPORT which
were missing previously. The data tests from the previous commit are
also added to `libstatic` and `libshared_and_static` for consistency.
Note that there are no exported members of exported classes, as these
are not allowed on Windows.
This directory contains tests that run CMake to configure a project
but do not actually build anything. To add a test:
1. Add a subdirectory named for the test, say ``<Test>/``.
2. In ``./CMakeLists.txt`` call ``add_RunCMake_test`` and pass the
test directory name ``<Test>``.
3. Create script ``<Test>/RunCMakeTest.cmake`` in the directory containing::
include(RunCMake)
run_cmake(SubTest1)
...
run_cmake(SubTestN)
where ``SubTest1`` through ``SubTestN`` are sub-test names each
corresponding to an independent CMake run and project configuration.
One may also add calls of the form::
run_cmake_command(SubTestI ${CMAKE_COMMAND} ...)
to fully customize the test case command-line.
Alternatively, if the test is to cover running ``ctest -S`` then use::
include(RunCTest)
run_ctest(SubTest1)
...
run_ctest(SubTestN)
and create ``test.cmake.in``, ``CTestConfig.cmake.in``, and
``CMakeLists.txt.in`` files to be configured for each case.
4. Create file ``<Test>/CMakeLists.txt`` in the directory containing::
cmake_minimum_required(...)
project(${RunCMake_TEST} NONE) # or languages needed
include(${RunCMake_TEST}.cmake)
where ``${RunCMake_TEST}`` is literal. A value for ``RunCMake_TEST``
will be passed to CMake by the ``run_cmake`` macro when running each
sub-test.
5. Create a ``<Test>/<SubTest>.cmake`` file for each sub-test named
above containing the actual test code. Optionally create files
containing expected test results:
``<SubTest>-result.txt``
Process result expected if not "0"
``<SubTest>-stdout.txt``
Regex matching expected stdout content
``<SubTest>-stderr.txt``
Regex matching expected stderr content, if not "^$"
``<SubTest>-check.cmake``
Custom result check.
Note that trailing newlines will be stripped from actual and expected
test output before matching against the stdout and stderr expressions.
The code in ``<SubTest>-check.cmake`` may use variables
``RunCMake_TEST_SOURCE_DIR``
Top of test source tree
``RunCMake_TEST_BINARY_DIR``
Top of test binary tree
and an failure must store a message in ``RunCMake_TEST_FAILED``.
