Look for a <SubTest>-check.cmake script and load it to check side
effects of the sub test. Provide it with the test source and build tree
paths in variables. Check for a failure message in a result variable.
Since commit ed1ea24c (Fix INSERT to allow inserting to empty list,
2006-05-15) the list command allows insertion into an empty list at
index 0. Fix rejection of insertion at non-zero (negative) indices to
present an error message instead of crashing.
While at it, fix the error message of the GET and REMOVE_AT operations
when the list is empty to not present a bogus allowed range.
Add a "RunCMake.list" test to cover failure cases on empty lists.
Teach the RunCMake.ObjectLibrary test to verify that languages used in
an OBJECT library are propagated to targets that use it so that the
languages can be included in link analysis.
Add "RunCMake.ObjectLibrary" test to verify that unsupported use cases
are rejected with errors:
* An OBJECT library may not reference another object library
* An OBJECT library may not be referenced in target_link_libraries
* An OBJECT library may not contain non-compiling sources
* An OBJECT library may not have pre/post build/link commands
* An OBJECT library may not be installed, exported, or imported
Also verify that invalid $<TARGET_OBJECTS:...> expressions are
diagnosed.
The CMakeCommands.build_command test performs output/error checking
so move it over to RunCMake to re-use the generalized infrastrucure.
This is the only test left using Tests/CMakeCommands/CMakeLists.txt
so remove it.
The CMakeOnly directory added by commit 9a20abf0 (Add infrastructure for
CMake-only tests, 2012-01-11) was sufficient only for tests that always
run CMake to successfully configure a project. Later commit eeaaffcb
(find_package: Test error and warning messages in failure cases,
2012-02-28) added a sample test that covers failure cases.
Generalize the above to create new "RunCMake" test infrastructure that
can run CMake multiple times for a single project with different
variations and check for expected result/stdout/stderr. Allow for both
successful and failing CMake project configuration cases. This will be
useful to test error messages and failure behavior.
