Brad King 71910b3fd4 Fix find_package() when <pkg>_DIR is wrong
When <pkg>_DIR is set to an incorrect version we search again and store
the result in the variable, even if it is <pkg>_DIR-NOTFOUND.

There was a bug in the case when the new search does not find anything
and the old value came from a cache entry with UNINITALIZED type.  The
command used to try to load a package configuration file from the last
place searched, and would leave the old wrong value in the entry.  This
commit fixes the behavior to avoid trying to load a missing file and to
set the value to <pkg>_DIR-NOTFOUND as expected.

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 6c59b924d2 Use BeAPI for per-user package registry on Haiku
Applications on Haiku are discouraged from storing their data in $HOME.
This teaches export(PACKAGE) and find_package() to use the BeAPI on
Haiku to store the package registry instead of using ~/.cmake/packages.

See issue #9603.

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 ed0650f6ae Teach find_package to search a "package registry"
A common user workflow is to build a series of dependent projects in
order.  Each project locates its dependencies with find_package.  We
introduce a "user package registry" to help find_package locate packages
built in non-standard search locations.

The registry explicitly stores locations of build trees providing
instances of a given package.  There is no defined order among the
locations specified.  These locations should provide package
configuration files (<package>-config.cmake) and package version files
(<package>-config-version.cmake) so that find_package will recognize the
packages and test version numbers.

Brad King be24db77d0 Fix find_package for cmake-gui registry entry
The find_package commands looks at the "WhereBuild" registry entries
created by CMakeSetup and cmake-gui hoping that the project was recently
built.  CMakeSetup created WhereBuild1..WhereBuild10 but cmake-gui
creates WhereBuild0-WhereBuild9.

This fixes find_package to look at WhereBuild0 so that the most recently
configured project can be found.  It is important in the case that the
package to be found was the last one configured in cmake-gui but the
current project that is finding it is configured from the command line.

Brad King c332e0bf3c ENH: Isolate policy changes in included scripts
Isolation of policy changes inside scripts is important for protecting
the including context.  This teaches include() and find_package() to
imply a cmake_policy(PUSH) and cmake_policy(POP) around the scripts they
load, with a NO_POLICY_SCOPE option to disable the behavior.  This also
creates CMake Policy CMP0011 to provide compatibility.  See issue #8192.

Alexander Neundorf ef3e48c3d5 ENH: when trying to find a FooConfig.cmake file, if in the directory pointed
to by the Foo_DIR variable there is no FooConfig.cmake file, then instead of
abort and complain that the user should set or clear the Foo_DIR variables,
just search for the file and discard the old Foo_DIR contents

The tests succeed, ok by Brad.

Brad King 3958b3e112 ENH: Teach find_package about more install dirs
We now search in

  <prefix>/<name>*/
  <prefix>/<name>*/(cmake|CMake)

when looking for package configuration files.  This is useful on Windows
since the Program Files folder is in CMAKE_SYSTEM_PREFIX_PATH.  These
paths are the Windows equivalent to the Apple convention application and
framework paths we already search.  See issue #8264.

Brad King 2d842b6798 BUG: find_package must push/pop policies
When the find_package command loads a <name>-version.cmake file to test
the package version it must prevent the version file from affecting
policy settings.  Therefore the policy settings must be pushed and
popped.

Brad King e51969ac49 ENH: Add useful search locations to find_package
This teaches find_package to search

for package configuration files.  Packages that do not already have
files in a <prefix>/lib/<name>* directory can use this location to avoid
cluttering the lib directory.

Brad King ae28ec9f24 ENH: Preserve <pkg>_FIND_XXX vars in find_package
When the find_package command loads a module it sets several
<pkg>_FIND_XXX variables to communicate information about the command
invocation to the module.  This restores the original state of the
variables when the command returns.  This behavior is useful when a
find-module recursively calls find_package with NO_MODULE so that the
inner call does not change the values in the find-module.
2008-12-09 10:08:54 -05:00
Brad King 25a5c34a62 ENH: Remove implicit NO_MODULE when recursing
Recently we taught find_package that the NO_MODULE option is implied
when it is recursively invoked in a find-module.  This behavior may be
confusing because two identical calls may enter different modes
depending on context.  It also disallows the possibility that one
find-module defers to another find-module by changing CMAKE_MODULE_PATH
and recursively invoking find_package.  This change reverts the feature.

environment.

Brad King 79e9b75558 ENH: Help recursive find_package calls in modules
These changes teach find_package to behave nicely when invoked

never be recursively loaded again.  Version arguments are automatically
forwarded.

leaving them unset.  This simplifies version number handling for find-

since some packages use them.

    between cmFindBase and cmFindPackageCommand.
  - Expand user path registry values up in cmFindCommon
    - Enables 32-/64-bit registry view for find_package
    - Disables registry expansion for paths not specified
      with the PATHS argument, which is not expected.
