Tests/ObjectLibrary: Do not enable CXX in subdirectories In commit b237dbd8 (Xcode: Fix object library references in multi-project trees, 2012-08-03) we accidentally enabled CXX in the subdiretories of this test by invoking project() with only one argument. The top-level directory of the test enables only C, so do this in the subdirectories too.

Test OBJECT library success cases Add "ObjectLibrary" test to build and use OBJECT libraries. Build multiple object libraries in separate directories with different flags. Use a custom command to generate a source file in one OBJECT library. Reference the OBJECT libraries for inclusion in a STATIC library, a SHARED library, and an EXECUTABLE target. Use the static and shared libraries each in executables that end up using the object library symbols. Verify that object library symbols are exported from the shared library.

# Add -fPIC so objects can be used in shared libraries.
Tests: Resolve TODO comment left in ObjectLibrary test We now have a generic way to add -fPIC without explicitly modifying CMAKE_C_FLAGS, so use it.

Fix ObjectLibrary test on Watcom The Watcom compiler interprets "-DB" as option -db generate browsing information so define "A_DEF" and "B_DEF" instead of just "A" and "B". Skip CMAKE_SHARED_LIBRARY_C_FLAGS for Watcom because it is set to -bd build Dynamic link library which adds a DLL entry point to each object.

add_library: Allow arbitrary non-linked sources in OBJECT libraries Loosen this restriction on OBJECT libraries to allow source files of any name to be generated by custom commands or listed for reference in IDE projects so long as they would not affect linking of a normal library. Update the rejection message to be more specific about the looser restriction. Extend the ObjectLibrary test to cover a ".cmake" file generated by a custom command in an OBJECT library.

Whitelist target types in target_{include_directories,compile_definitions} Setting include directories or compile definitions on a target created with add_custom_target does not make sense.
