      Compute implicit include directories from compiler output · 5990ecb7
      chuck cranor authored and Brad King's avatar Brad King committed 
       - CMakeParseImplicitIncludeInfo.cmake: new parser that extracts the
   compiler's include path from verbose output.  If the parser cannot
   parse the output, we fall back to the old behavior.  On osx we skip
   over framework directories (handled elsewhere).

 - CMakeDetermineCompilerABI.cmake:
     - use verbose flag in try_compile for ${src}
     - use new cmake_parse_implicit_include_info() to attempt extract
       implicit include directory path and if successful set
        CMAKE_${LANG}_IMPLICIT_INCLUDE_DIRECTORIES

 - CMakeCCompiler.cmake.in and CMakeCXXCompiler.cmake.in - preserve
   CMAKE_${LANG}_IMPLICIT_INCLUDE_DIRECTORIES value between runs in
   the same way CMAKE_${LANG}_IMPLICIT_LINK_DIRECTORIES is preserved

 - Tests/RunCMake/ParseImplicitIncludeInfo: tests for parse
   based on the older Tests/CMakeTests/ImplicitLinkInfoTest.cmake.in.
   The test runs a set of verbose compiler outputs collected from
   various machines through the parser and checks the results.  New
   compiler files can be added by dropping input/output files in the
   ParseImplicitIncludeInfo/data subdirectory and then adding the new set
   of files to the ${targets} list in ParseImplicitIncludeInfo.cmake.
   There is a helper CMakeLists.txt in ParseImplicitIncludeInfo/data
   that can help with the generation of test input files.
   NOTE: the standard cmake pre-commit hook rejects verbose compiler
   output with trailing spaces... you have to manually edit them out.
   This shouldn't impact the test.

Note that both the parser and the test code can use CMAKE_${LANG}_COMPILER_*
variables such as ${CMAKE_CXX_COMPILER_ID} to decide how to parse
verbose compiler output.  For the test code, this requires us to
save the variables values in the test input files.

Fixes: #16291

      CMakeDetermineCompilerABI: set locale to C for try_compile() · d751d2d2
      chuck cranor authored and Brad King's avatar Brad King committed 
      Have CMakeDetermineCompilerABI set the locale to C before calling
try_compile().  This is for the implicit include path parser to
keep all the verbose compiler messages in English so we can parse
it.   See #18784 for discussion.

      CMakeDetermineCompilerABI: pass verbose flag during compilation · c765ae49
      Brad King authored 
      Default to the same flag that is used for verbose link information, but
provide another internal platform information variable to use a
compilation-specific variant.  Populate it for CUDA where we use a
different compiler for compilation and linking and therefore need
different flags.
