v0.4.0

[Version 0.4.0] - Release date 2021-04-09

Added

• Added variable BLT_CMAKE_IMPLICIT_LINK_DIRECTORIES_EXCLUDE for filtering
  link directories implicitly added by CMake. See the following example host-config:
  host-configs/llnl/blueos_3_ppc64le_ib_p9/clang@upstream_nvcc_c++17.cmake
• Added support for clang-tidy static analysis check
• Added ability to change the output name of an executable via the OUTPUT_NAME
  parameter of blt_add_executable
• Added user option for enforcing specific versions of autoformatters - the new options are
  BLT_REQUIRED_ASTYLE_VERSION, BLT_REQUIRED_CLANGFORMAT_VERSION, and BLT_REQUIRED_UNCRUSTIFY_VERSION
• Added HEADERS to blt_add_executable. This is important for build system dependency tracking
  and IDE folder support.
• Added support for formatting Python code using YAPF.
• Added new blt_import_library macro that creates a real CMake target for imported libraries,
  intended to be used instead of blt_register_library whenever possible
• Added new blt_patch_target macro to simplify modifying properties of an existing CMake target.
  This macro accounts for known differences in compilers, target types, and CMake releases.
• Added support for formatting CMake code using cmake-format.
• Added an EXPORTABLE option to blt_import_library that allows imported libraries to be
  added to an export set and installed.
• Added FRUIT's MPI parallel unit test reporting to BLT's internal copy of FRUIT
• CUDA device links for object libraries can be enabled with the existing CUDA_RESOLVE_DEVICE_SYMBOLS
  target property.

Changed

• MPI Support when using CMake 3.13 and newer: MPI linker flags are now passed
  as single string prefixed by SHELL: to prevent de-duplication of flags
  passed to target_link_options.
• For HIP-dependent builds, only add HCC include directory if it exists.
• HIP CMake utilities updated to AMD's latest version
• Updated add_code_coverage_target to blt_add_code_coverage_target, which now supports
  user-specified source directories
• Code coverage targets leave LCOV-generated files intact for later use; these files will
  still be removed by make clean

Fixed

• ClangFormat checks now support multiple Python executable names
• Prefixed blt_register_library() internal variables with _ to avoid collision
  with input parameters.
• Turn off system includes for registered libraries when using the PGI compiler
• Removed unneeded SYSTEM includes added by googletest that was causing problems
  in PGI builds (BLT was adding them already to the register library calls)
• Removed variable BLT_CMAKE_CUDA_IMPLICIT_LINK_DIRECTORIES_EXCLUDE, functionality now
  provided for all languages using BLT_CMAKE_IMPLICIT_LINK_DIRECTORIES_EXCLUDE variable
• ClangQuery was being auto-enabled in cases where no checker directories where defined.
  This caused a crash. blt_add_clang_query_target learned parameter CHECKER_DIRECTORIES
  and blt_add_code_checks learned parameter CLANGQUERY_CHECKER_DIRECTORIES. Both still
  respect BLT_CLANGQUERY_CHECKER_DIRECTORIES.
• It is now a fatal error to supply CLANGFORMAT_CFG_FILE plus
  ASTYLE_CFG_FILE or UNCRUSTIFY_CFG_FILE arguments to
  blt_add_code_checks; previously, these combinations were implied to
  be errors in BLT documentation, but BLT would not return an error in
  those cases.
• blt_patch_target no longer attempts to set system include directories when a target
  has no include directories
• Header-only libraries now can have dependencies via DEPENDS_ON in blt_add_library
• Added a workaround for include directories of imported targets on PGI. CMake was
  erroneously marking them as SYSTEM but this is not supported by PGI.
• Check added to make sure that if HIP is enabled with fortran, the LINKER LANGUAGE
  is not changed back to Fortran.
• Executables that link to libraries that depend on hip/hip_runtime/cuda/cuda_runtime
  will automatically be linked with the HIP or CUDA (NVCC) linker
• Patched an issue with the FindHIP macros that added the inclusive scan of specified
  DEFINEs to compile commands
• Re-added previous OpenMP flag patching logic to maintain compatibility with BLT-registered libraries
