      Simplify CMake per-source license notices · 86578ecc
      Brad King authored
      Per-source copyright/license notice headers that spell out copyright holder
      names and years are hard to maintain and often out-of-date or plain wrong.
      Precise contributor information is already maintained automatically by the
      version control tool.  Ultimately it is the receiver of a file who is
      responsible for determining its licensing status, and per-source notices are
      merely a convenience.  Therefore it is simpler and more accurate for
      each source to have a generic notice of the license name and references to
      more detailed information on copyright holders and full license terms.
      Our `Copyright.txt` file now contains a list of Contributors whose names
      appeared source-level copyright notices.  It also references version control
      history for more precise information.  Therefore we no longer need to spell
      out the list of Contributors in each source file notice.
      Replace CMake per-source copyright/license notice headers with a short
      description of the license and lin...

      Revert "Disable shared library support when compiler links statically" (#15855) · 9682de56
      Brad King authored
      In commit v3.4.0-rc1~18^2 (Disable shared library support when compiler
      links statically, 2015-09-30) we tried to detect when the compiler is
      not capable of linking shared libraries (possibly due to flags in use).
      However, the approach is not robust against flags like `-nostdlib`.
      Revert it for now pending another solution to the original problem.

      Disable shared library support when compiler links statically · 8b4873a1
      Brad King authored
      When a user or a compiler wrapper adds '-static' to the compiler flags
      then it will always link static binaries.  Detect this from the compiler
      id binary and disable TARGET_SUPPORTS_SHARED_LIBS.  This will prevent
      projects from accidentally adding shared libraries when the toolchain
      does not support them.  It also helps CMake avoid linking with flags
      that require shared libraries to be supported.

      Support duplicate object names in large archives (#14874) · 1ec6485c
      Brad King authored
      Generalize the change from commit 39d0ade0 (Windows-GNU: Support
      duplicate object names in large archives, 2014-04-14) to the default
      archive rules.  These rules have used an incremental append approach
      since commit v2.8.0~1856 (Build large archives incrementally,
      2008-08-04).  Switch from "ar r" to "ar q" to be sure we always append
      objects instead of replacing them.

      Prefer CMAKE_MAKE_PROGRAM over CMAKE_BUILD_TOOL (#14548) · 4ac75fdf
      Brad King authored
      Historically these were both added for the Makefile and Visual Studio
      generators, respectively.  Later the VS generators started using the
      CMAKE_MAKE_PROGRAM cache entry to find the IDE build tool, and the
      CMAKE_BUILD_TOOL was simply set as an alias.
      Fix the documentation to explain that CMAKE_MAKE_PROGRAM is the modern
      variable and that CMAKE_BUILD_TOOL is the compatibility alias, not the
      other way around.  Replace uses of CMAKE_BUILD_TOOL with
      CMAKE_MAKE_PROGRAM in CMake-provided modules.  Nothing needs to lookup
      CMAKE_BUILD_TOOL in the cache, so simply set it as a normal variable.

      Even though this variable gets set to CMAKE_<LANG>_COMPILER-NOTFOUND when
      the compiler is not found, CMake<LANG>Compiler.cmake gets removed by
      cmGlobalGenerator::EnableLanguage so in try compiles the value is empty.
      Quote references to the variable in

      Add platform variables for position independent code flags · 31d7a0f2
      Stephen Kelly authored
      Store in new platform variables
      flags for position independent code generation.
      In almost all cases, this means duplication of the
      CMAKE_SHARED_LIBRARY_${lang}_FLAGS for the _PIC case and using the
      assumed pie equivalent for the _PIE case.  Note that the GNU compiler
      has supported -fPIE since 3.4 and that there is no -fPIC on GNU for
      Windows or Cygwin.
      There is a possibility that the _PIE variables are not correct.
      However, as there is no backwards compatibility to be concerned about
      (as the POSITION_INDEPENDENT_CODE property is not used anywhere yet),
      the current state suffices.

      Support building shared libraries or modules without soname (#13155) · e1409ac5
      Modestas Vainius authored
      Add a boolean target property NO_SONAME which may be used to disable
      soname for the specified shared library or module even if the platform
      supports it.  This property should be useful for private shared
      libraries or various plugins which live in private directories and have
      not been designed to be found or loaded globally.
      Replace references to <CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG> and
      hard-coded -install_name flags with a conditional <SONAME_FLAG> which is
      expanded to the value of the CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG
      definition as long as soname supports is enabled for the target in
      question.  Keep expanding CMAKE_SHARED_LIBRARY_SONAME_${LANG}_FLAG in
      rules in case third party projects still use it.  Such projects would
      not yet use NO_SONAME so the adjacent <TARGET_SONAME> will always be
      expanded.  Make <TARGET_INSTALLNAME_DIR> NO_SONAME aware as well.  Since
      -install_name is soname on OS X, this should not be a problem if this
      variable is expanded only if soname is enabled.
      The Ninja generator performs rule variable substitution only once
      globally per rule to put its own placeholders.  Final substitution is
      performed by ninja at build time.  Therefore we cannot conditionally
      replace the soname placeholders on a per-target basis.  Rather than
      omitting $SONAME from rules.ninja, simply do not write its contents for
      targets which have NO_SONAME.  Since 3 variables are affected by
      soname is enabled.

      If CXX or Fortran is enabled before C then the values of

      Teach the COnly and CxxOnly tests to build MODULE libraries.  The latter

      Load platform files named in CMAKE_<lang>_ABI_FILES for each language

      In commit 295b5b60 (Honor CMAKE_USER_MAKE_RULES_OVERRIDE in try_compile,

      a try_compile project.  If the variable contains a relative path it must
      be treated with respect to the file where it is first used.  Ensure that
      the value is converted to a full path so that it is correctly referenced
      in the try_compile projects.

      Reset platform/compiler info status for each language · 20f49730
      Brad King authored
      In each CMake<lang>Information.cmake file we use an _INCLUDED_FILE
      variable to track whether a compiler information file has been loaded.
      Reset this variable for each language.
      This fixes Fortran under VS generators with the Intel plugin.
      Previously the variable would be left set true from C and C++ and then
      Fortran would not load old-style files like Platform/Windows-ifort.

      Use work-around from bug 4772 for C++ and Fortran · d0c03f80
      Brad King authored
      The commit "fix for bug 4772" added a work-around to CMakeCInformation
      for platform config files that put compiler information in the system
      file (like SunOS flags for GCC).  This commit adds the same work-around
      for CXX and Fortran.  It is necessary to support enabling these
      languages separately from C in other subdirectories.
      The commit "Avoid (Unix|Windows)Paths.cmake multiple include" added
      include blockers that prevent the files from multiple inclusion, so it
      is safe to include the system information files from every language.
      See issue #4772 and issue #9656.
