Daniele E. Domenichelli bc280f1c81 set: Fix handling of empty value with PARENT_SCOPE
Just as

  set(VAR "")

sets VAR to an empty string in the current scope, the code

  set(VAR "" PARENT_SCOPE)

is documented to set the variable to an empty string in the parent
scope.  Fix the implementation to make it so.

Daniele E. Domenichelli 20afbd5e03 set: Handle value-less PARENT_SCOPE explicitly
The code "set(VAR PARENT_SCOPE)" unsets VAR in the parent scope.
Implement this case explicitly next to where "set(VAR)" is explicitly
handled to unset VAR in the current scope.

Kitware Robot 7bbaa4283d Remove trailing whitespace from most CMake and C/C++ code
Our Git commit hooks disallow modification or addition of lines with
trailing whitespace.  Wipe out all remnants of trailing whitespace
everywhere except third-party code.

Run the following shell code:

git ls-files -z -- \
 bootstrap doxygen.config '*.readme' \
 '*.c' '*.cmake' '*.cpp' '*.cxx' \
 '*.el' '*.f' '*.f90' '*.h' '*.in' '*.in.l' '*.java' \
 '*.mm' '*.pike' '*.py' '*.txt' '*.vim' |
egrep -z -v '^(Utilities/cm|Source/(kwsys|CursesDialog/form)/)' |
egrep -z -v '^(Modules/CPack\..*\.in)' |
xargs -0 sed -i 's/ \+$//'

Brad King 9a77f65da7 Remove CMake Policy CMP0015 until it is revised
We revert commit "Create CMake Policy CMP0015 to fix set(CACHE)" because
the NEW behavior of the policy breaks a valid use case:

  # CMakeLists.txt
  option(BUILD_SHARED_LIBS "..." ON)
  add_library(mylib ...)
  set(BUILD_SHARED_LIBS OFF) # we want only mylib to be shared
  add_subdirectory(ThirdParty)

  # ThirdParty/CMakeLists.txt
  option(BUILD_SHARED_LIBS "..." ON)
  # uh, oh, with NEW behavior this dir uses shared libs!!!

We'll re-introduce the policy later with a different change in behavior
to resolve the motivating case, which was more subtle but less common.

See issue #9008.

Brad King 96afb12087 Convert CMake to OSI-approved BSD License
This converts the CMake license to a pure 3-clause OSI-approved BSD
License.  We drop the previous license clause requiring modified
versions to be plainly marked.  We also update the CMake copyright to
cover the full development time range.

Brad King b41a548d86 Add parentheses around '&&' between '||' for gcc
The GNU compiler warns about possible operator precedence mistakes and
asks for explicit parentheses (-Wparentheses).  We add the parentheses
to silence the warning.  This also fixes one real logic error in the
find_package() implementation by correcting expression evaluation order.

Brad King ee2b446c95 Create CMake Policy CMP0015 to fix set(CACHE)
The set(CACHE) and option() commands should always expose the cache
value.  Previously we failed to expose the value when it was already set
if a local variable definition hid it.  When set to NEW, this policy
tells the commands to always remove the local variable definition to
expose the cache value.  See issue #9008.
