Brad King 3a790251f4 Document and test find_package <pkg>_DIR env var
The find_package(<pkg>) command checks the <pkg>_DIR environment
variable.  This commit documents and tests the feature.

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 07f029d6ef Test the user package registry
We teach the FindPackageTest to build a sample project that stores its
build tree in the user package registry using export(PACKAGE), and then
find it with find_package.

Brad King bb2c08546c ENH: Test find_package re-find feature
Recently we taught find_package to re-find a package if its
<package>_DIR result variable was set to a location not containing the
package (instead of reporting an error as before).  This tests the
feature.

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 63e186a8e6 ENH: Strengthen FindPackageTest version check
The previous change to test finding in lib/cmake/<name>* weakened the
versioned find tests.  Since the lib/cmake paths are searched before
lib/<name>* paths the previous change skipped requiring the command to
ignore zot-3.0 when finding zot-3.1.  This change restores that and adds
zot-4.0 to test the lib/cmake path.

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

  <prefix>/(share|lib)/cmake/<name>*/

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 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 4fa96dbf95 ENH: Add version comparison to if() command
Provide VERSION_LESS, VERSION_EQUAL, and VERSION_GREATER operators in
the if() command.  This simplifies component-wise comparison of version
numbers in the form "major[.minor[.patch[.tweak]]]".

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 41c2895b75 ENH: Added version support to Config mode of find_package command.
- Added EXACT option to request an exact version.
  - Enforce version using check provided by package.
  - Updated FindPackageTest to test versioning in config mode.

Brad King f41b1e8e91 ENH: Implement version support in the find_package command module mode. Version numbers provided to the command are converted to variable settings to tell the FindXXX.cmake module what version is requested. This addresses issue #1645. 2008-01-21 08:48:33 -05:00

Alexander Neundorf 0398d8ad38 ENH: add support for CMAKE_FIND_PREFIX_PATH as discussed with Brad.
CMAKE_FIND_PREFIX_PATH is both an environment variable and a cmake variable,
which is a list of base directories where FIND_PATH, FIND_FILE, FIND_PROGRAM
and FIND_LIBRARY will search in the respective subdirectories
