v0.7.0

Added

• Added WORKING_DIRECTORY option to blt_add_test and blt_add_benchmark.
• Added BLT_CXX_FILE_EXTS variable (split out of BLT_C_FILE_EXTS) for use in modified blt_split_source_list_by_language macro.

Changed

• Modified blt_convert_to_system_includes to handle multiple targets and recursively update includes for dependencies.
• Modified blt_split_source_list_by_language to accept a CXX_LIST argument for splitting out C and CXX sources. If not specified, the C_LIST will contain both C and C++ sources.
• HIP support now uses enable_language(HIP), and specifying a HIP compiler must use the variable CMAKE_HIP_COMPILER.
• Updated GoogleBenchmark to 1.9.1

Fixed

• Removed GoogleTest, GoogleMock, and GoogleBenchmarks calling CMake's GNUInstallDirs
  which was causing non-deterministic install variables depending on your combination of
  static/shared libraries and if any of the previously mentioned TPLs were enabled.
• Enable C language support and emit a warning when GoogleTest or GoogleMock are enabled but
  not the C language.
• Guard HIP C smoketest against projects that don't enable C as a language in their projects.
• Changes benchmark custom target run_benchmarks to exclusively run benchmarks (not other general tests).
• Fix HIP smoketests to fail on HIP errors.
• Add -Wno-tautological-compare to GoogleTest/Mock/Benchmark for IntelLLVM compilers to silence
  warning.
