* find_package: Use PackageName_ROOT variables as search prefixesBrad King2018-03-161-12/+6
| | | | | | | | | | | | | | | | | | | This feature was originally added by commit v3.9.0-rc1~71^2~2 (find_*: Add a new PackageRoot search path group, 2017-05-03) and documented by commit v3.9.0-rc1~71^2 (find_*: Add docs for PackageRoot search path group, 2017-05-03). However, we had to disable the feature and remove the documentation in commit v3.9.1~2^2 (find_*: Disable the PACKAGE_ROOT search path group for CMake 3.9, 2017-08-08) due to breaking projects that used `PackageName_ROOT` variables themselves. Add policy `CMP0074` to restore the `PackageName_ROOT` variable behavior in a compatible way. Also revise the stack of root paths to store the paths themselves rather than the package names. This way the policy can be considered at the `find_package` call site instead of individual `find_` calls inside a find module. Co-Author: Chuck Atkins <chuck.atkins@kitware.com> Issue: #17144

* find_*: Disable the PACKAGE_ROOT search path group for CMake 3.9Brad King2017-08-081-0/+2
| | | | | | | | | | | | | | | | Disable the feature added by commit v3.9.0-rc1~71^2~2 (find_*: Add a new PackageRoot search path group, 2017-05-03) and remove documentation added by commit v3.9.0-rc1~71^2 (find_*: Add docs for PackageRoot search path group, 2017-05-03). Unfortunately the name `<pkg>_ROOT` may already be set by projects for their own incompatible purposes. Disable the behavior change for now to fix the regression for CMake 3.9. We can restore it later with a policy. In order to keep the implementation and tests working, add an undocumented variable we can use in the tests to enable the behavior before the policy is introduced. Fixes: #17144
* find_*: Honor PATH_SUFFIXES in PackageName_ROOT pathsBrad King2017-07-111-0/+2
| | | | | | | This was accidentally forgotten in commit v3.9.0-rc1~71^2~2 (find_*: Add a new PackageRoot search path group, 2017-05-03). Fixes: #17052
* find_*: Add a new PackageRoot search path groupChuck Atkins2017-05-161-0/+22
| | | | | | The new PackageRoot search path group allows the PackageName_ROOT cmake and environment variables to be used as search prefixes for all find_* commands called from within a find module

* Simplify CMake per-source license noticesBrad King2016-09-271-11/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Per-source copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong. Precise contributor information is already maintained automatically by the version control tool. Ultimately it is the receiver of a file who is responsible for determining its licensing status, and per-source notices are merely a convenience. Therefore it is simpler and more accurate for each source to have a generic notice of the license name and references to more detailed information on copyright holders and full license terms. Our `Copyright.txt` file now contains a list of Contributors whose names appeared source-level copyright notices. It also references version control history for more precise information. Therefore we no longer need to spell out the list of Contributors in each source file notice. Replace CMake per-source copyright/license notice headers with a short description of the license and links to `Copyright.txt` and online information available from "https://cmake.org/licensing". The online URL also handles cases of modules being copied out of our source into other projects, so we can drop our notices about replacing links with full license text. Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority of the replacements mechanically. Manually fix up shebang lines and trailing newlines in a few files. Manually update the notices in a few files that the script does not handle.

* Restore find_(library|file|path) search of PATH itselfBrad King2016-07-111-4/+2
| | | | | | | | | | | The fix in commit commit v3.6.0-rc1~82^2 (Drop find_(library|file|path) prefixes from PATH on non-Windows, 2016-05-09) aggressively dropped search of the entries in PATH itself in addition to the prefixes derived from it. This regresses find modules that (incorrectly) depended on the behavior, including some of our own modules such as FindImageMagick. Restore the search of entries in PATH itself. If we want to drop it later we will need to do so with a policy. Fixes #16192.

* Drop find_(library|file|path) prefixes from PATH on non-WindowsBrad King2016-05-091-2/+8
| | | | | | | | | | | Since commit v3.3.0-rc1~430^2 (Teach find_(library|file|path) to get prefixes from PATH, 2015-02-18) we search in <prefix>/include and <prefix>/lib directories for prefixes with bin directories in the PATH environment variable. The motivation was to support MSYS, MinGW and similar Windows platforms in their default environments automatically. At the time this behavior was thought to be worthwhile in general.

* Remove `//------...` horizontal separator commentsBrad King2016-05-091-8/+0
| | | | | | | | | | | | | | | | | | | | | | | | Modern editors provide plenty of ways to visually separate functions. Drop the explicit comments that previously served this purpose. Use the following command to automate the change: $ git ls-files -z -- \ "*.c" "*.cc" "*.cpp" "*.cxx" "*.h" "*.hh" "*.hpp" "*.hxx" | egrep -z -v "^Source/cmCommandArgumentLexer\." | egrep -z -v "^Source/cmCommandArgumentParser(\.y|\.cxx|Tokens\.h)" | egrep -z -v "^Source/cmDependsJavaLexer\." | egrep -z -v "^Source/cmDependsJavaParser(\.y|\.cxx|Tokens\.h)" | egrep -z -v "^Source/cmExprLexer\." | egrep -z -v "^Source/cmExprParser(\.y|\.cxx|Tokens\.h)" | egrep -z -v "^Source/cmFortranLexer\." | egrep -z -v "^Source/cmFortranParser(\.y|\.cxx|Tokens\.h)" | egrep -z -v "^Source/cmListFileLexer\." | egrep -z -v "^Source/cm_sha2" | egrep -z -v "^Source/(kwsys|CursesDialog/form)/" | egrep -z -v "^Utilities/(KW|cm).*/" | xargs -0 sed -i '/^\(\/\/---*\|\/\*---*\*\/\)$/ {d;}' This avoids modifying third-party sources and generated sources.

* | Teach find_(library|file|path) to get prefixes from PATH (#15370)Brad King2015-02-191-0/+1
|/ | | | | | | | | The find_package command already knows how to compute installation prefixes from PATH. Use the same approach to establish prefixes for find_library, find_file, and find_path to use to look in directories like "<prefix>/lib[/<arch>]" and "<prefix>/include" for libraries and headers. This will reduce the amount of configuration end users need to do to establish a work environment rooted under a specific prefix.

* Use containers of labeled search paths instead of individual membersChuck Atkins2014-11-121-24/+34
| | | | | | | Manage classes of search paths in labeled containers. This removes the need to have a seperate member variable for each type of search path, but also allows path types to be grouped togethor in various different ways and manipulated as subsets of the full set of search paths.
* Encapsulate search path manipulation functions into a seperate class.Chuck Atkins2014-11-111-143/+34
| | | | | | The functions for adding the various different types of paths have been factored out into a new class, cmSearchPath. It is to be used as a helper container class for the various find_* commands.
* Refactor and seperate search path construction for find commandsChuck Atkins2014-11-111-122/+133
| | | | | | | Prior to this commit, the set of search paths to traverse for find commands was incrementally constructed. This change allows each group of paths, i.e. CMakeVariablePaths, UserHintsPaths, SystemEnvironmentPaths, etc. to be constructed and manipulated independently, and then all combined togethor.
* Remove some c_str() calls.Stephen Kelly2014-03-111-4/+4

* Drop compatibility with CMake < 2.4Brad King2013-10-231-18/+0
| | | | | | | | | | | | Drop all behavior activated by setting CMAKE_BACKWARDS_COMPATIBILITY to a value lower than 2.4, and generate an error when projects or the user attempt to do so. In the error suggest using a CMake 2.8.x release. Teach cmake_minimum_required to warn about projects that do not require at least CMake 2.4. They are not supported by CMake >= 3.0. Replace the documentation of CMAKE_BACKWARDS_COMPATIBILITY with a reference to policy CMP0001.

* find_library: Optionally consider all names in each directoryBrad King2012-09-251-0/+15
| | | | | | | When more than one value is given to the NAMES option this command by default will consider one name at a time and search every directory for it. Add a NAMES_PER_DIR option to tell this command to consider one directory at a time and search for all names in it.

* Refactor find_* command final path list computationBrad King2011-09-231-5/+1
| | | | | | | All find_* commands re-root the list of paths and then add trailing slashes. Factor this pair of calls out into a dedicated method. The new method would be the only caller to AddTrailingSlashes, so subsume that method into it.
