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.
# TODO: Need property for this.
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.

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.
