This reverts commit 2c3654c3de.

The removal of some tests added in commit 77cecb77 (Add includes and compile
definitions with target_link_libraries., 2012-11-05) are also squashed
into this commit.

Brad King 179f495602 find_package: Reword <package>_NO_INTERFACES documentation 2013-02-01 10:30:57 -05:00
Stephen Kelly 2c3654c3de Add a way to exclude INTERFACE properties from exported targets.
Projects set interface requirements upstream, and existing
downstreams use of target_link_libraries will consume those interfaces.

This can create a backward compatibility concern as the result may
be changing the order of include directories of downstreams, or another
side-effect of using the INTERFACE properties.

Provide a way for them to emulate the behavior of a version-based
policy in the config file.

Alex Neundorf 6f50a04cc1 exports: define a CMAKE_FIND_PACKAGE_NAME var set by find_package()
This way the name of the searched package can be accessed in find-modules,
config-files and more importantly in generated target export files.
This is now used when a target export file detects that a required
target does not exist.

Brad King 6c12e820b8 find_package: Document <package>_FIND_* variables (#13142)
When loading a find module or package config file the find_package

Modules/readme.txt file which is not distributed.  Document the
behavior explicitly in the main find_package documentation.

Alex Neundorf 16c0c7376c find_package: allow <pkg>Config.cmake to set <pkg>_FOUND to FALSE
Before, find_package in Config mode always set Foo_FOUND to true if the
Config file has been found and could be executed.
If the Config file itself detected some problem, like a missing dependency,
it did not have a way to signal to the outside that the package is not working.
With this patch, if a Config file sets Foo_FOUND to FALSE, this is taken into
account and not overridden.

Alex Neundorf 7d67dcf52b find_package: improve error message when no Find module is present
Explain exactly why CMake is looking for a package configuration file
and who is expected to provide what:

 CMake Error at CMakeLists.txt:7 (find_package):
  By not providing "Find<pkg>.cmake" in CMAKE_MODULE_PATH the caller
  has asked CMake to find a package configuration file provided by
  "<pkg>", but CMake did not find one.

  Could not find a package configuration file provided by "<pkg>"
  with any of the names:

    <pkg>Config.cmake
    <pkg>-config.cmake

  Add the installation prefix of "<pkg>" to CMAKE_PREFIX_PATH or
  set "<pkg>_DIR" to a directory containing one of the above files.
  If "<pkg>" provides separate development package or SDK be sure
  it has been installed.

The first paragraph explains how CMake is interpreting the intention of
the caller.  This puts the blame or credit at the call site in the
project code where it belongs both when it is a bug and when it is
intentional.  It can be dropped in NO_MODULE mode.

Alex Neundorf 33338781db Log the required package version and major improvement to FeatureSummary
find_package() now also stores the required version automatically, so it
can be used by FeatureSummary.cmake.
This was one of the requested features for setting up nightly builds
for KDE, since with this functionality it will be possible to write
a file at the end of each project which lists all required packages
and their versions. This file could then be compared for equality
with an older one and if something has changed the build maintainer
can be emailed.

In FeatureSummary.cmake there is now a new function feature_summary(),
which also allows to print the log to a file or into a variable.
It also allows to specify whether to append to a file or to write a new
one, and what information to log.

There was a bug in the case when the new search does not find anything

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.

The find_package commands looks at the "WhereBuild" registry entries

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 ae28ec9f24 ENH: Preserve <pkg>_FIND_XXX vars in find_package
When the find_package command loads a module it sets several

variables when the command returns.  This behavior is useful when a

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.

Brad King 0ae545ebad ENH: Add UNSUITABLE result to package version test
Package version test files may now declare that they are unsuitable for
use with the project testing them.  This is important when the version
being tested does not provide a compatible ABI with the project target
environment.

Brad King 79e9b75558 ENH: Help recursive find_package calls in modules
These changes teach find_package to behave nicely when invoked
recursively inside a find-module for the same package.  The module will
never be recursively loaded again.  Version arguments are automatically
forwarded.

Brad King 75f8d5aab7 ENH: Warn and ignore EXACT without version
If the find_package command is invoked with the EXACT option but without
a version, warn and ignore the option.

Brad King 994262e5cc ENH: Improve find_package version numbering
Make the number of version components specified explicitly available.
Set variables for unspecified version components to "0" instead of
leaving them unset.  This simplifies version number handling for find-
and config-modules.  Also support a fourth "tweak" version component
since some packages use them.

Brad King d8bfafeff8 ENH: Improve message for bad find_package call
Use the new-style error reporting mechanism to provide more context
information for a find_package call with a bad package name.  When the
package is not required, issue a warning instead of an error.

Brad King 2b96e0edab ENH: Teach find_package about lib64 paths
When find_package is about to look in <prefix>/lib, search first in
<prefix>/lib64 in cases that find_library would use lib64 paths.

Brad King d50785e26e ENH: Make find_* command search order more intuitive.
- The CMAKE_PREFIX_PATH and similar variables have both
    environment and CMake cache versions.
  - Previously the environment value was checked before the
    cache value.
  - Now the cache value is favored because it is more specific.

Brad King 5b406c9044 ENH: Add HINTS option to find_* commands.
- Hints are searched after user locations but before system locations
  - The HINTS option should have paths provided by system introspection
  - The PATHS option should have paths that are hard-coded guesses

2008-06-09 11:57:56 -04:00
Brad King 789c167b6f ENH: Refactor cmFindCommon, cmFindBase, and cmFindPackageCommand
- Add each part of the search order in a separate method.
  - Collect added paths in an ivar in cmFindCommon.
  - Move user path storage up to cmFindCommon and share
    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.

Alexander Neundorf 8d7b502337 ENH: add global properties for collecting enabled/disabled features during
the cmake run and add macros print_enabled/disabled_features() and
set_feature_info(), so projects can get a nice overview at the end of the
cmake run what has been found and what hasn't
FIND_PACKAGE() automatically adds the packages to these global properties,
except when used with QUIET
Maybe this can also be useful for packagers to find out dependencies of
projects.
