Brad King 4300de3e27 RC: Enable language after C, CXX, or Fortran is enabled (#15404)
The RC language is special in that it is automatically enabled
on Windows-based platforms when another primary language is
enabled.  Move enablement of RC from early in the enablement
of the other language to late.  This will allow it to use
information detected as part of enabling C, CXX, or Fortran.

Kitware Robot 9db3116226 Remove CMake-language block-end command arguments
Ancient versions of CMake required else(), endif(), and similar block
termination commands to have arguments matching the command starting the
block.  This is no longer the preferred style.

Run the following shell code:

for c in else endif endforeach endfunction endmacro endwhile; do
    echo 's/\b'"$c"'\(\s*\)(.\+)/'"$c"'\1()/'
done >convert.sed &&
git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' |
egrep -z -v '^(Utilities/cm|Source/kwsys/)' |
egrep -z -v 'Tests/CMakeTests/While-Endwhile-' |
xargs -0 sed -i -f convert.sed &&
rm convert.sed

Kitware Robot 77543bde41 Convert CMake-language commands to lower case
Ancient CMake versions required upper-case commands.  Later command
names became case-insensitive.  Now the preferred style is lower-case.

Run the following shell code:

cmake --help-command-list |
grep -v "cmake version" |
while read c; do
    echo 's/\b'"$(echo $c | tr '[:lower:]' '[:upper:]')"'\(\s*\)(/'"$c"'\1(/g'
done >convert.sed &&
git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' |
egrep -z -v '^(Utilities/cm|Source/kwsys/)' |
xargs -0 sed -i -f convert.sed &&
rm convert.sed

Stephen Kelly 31d7a0f2e3 Add platform variables for position independent code flags
Store in new platform variables

  CMAKE_${lang}_COMPILE_OPTIONS_PIC
  CMAKE_${lang}_COMPILE_OPTIONS_PIE

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.

Yaakov Selkowitz cd3a4f0025 Cygwin: Export all symbols with ENABLE_EXPORTS
The ENABLE_EXPORTS property exports all symbols from executables on
UNIX-like platforms, typically for use by plugins.  Honor this behavior
on Cygwin.  See issue #10122.

Brad King 3684f62340 Do not export all symbols from DLLs on Cygwin
In commit "use export all symbols on cygwin" (2003-01-21) we started
passing -Wl,--export-all-symbols when linking shared libraries.  Now
cygwin exports all symbols automatically if no symbols are explicitly
exported.  When symbols are explicitly exported we want to honor that
narrow interface.  Therefore this flag should not be passed.

Change based on patch from issue #10122.

Brad King 41024b006b Fix CMAKE_DL_LIBS on Cygwin
The variable should contain the name of a library needed to link the
symbol equivalent to dlopen.  On Cygwin no special library is needed,
and certainly not "gdi32".

Change based on patch from issue #10122.

Brad King e28c16b482 Split GNU compiler information files
This moves GNU compiler flags into new-style modules

  Compiler/GNU-<lang>.cmake
  Platform/<os>-GNU-<lang>.cmake

We use language-independent helper modules

  Compiler/GNU.cmake
  Platform/<os>-GNU.cmake

to define macros consolidating the information.
