* Misc. fixes for the Oracle / Sun compiler.Chuck Atkins2014-12-121-6/+9
| | | | | | A few pieces of code have some ambiguous type deduction that seems to resolve correctly for most compilers but not for the Oracle compiler. This makes those few instances more explicit.
* Remove some unneeded c_str calls.Stephen Kelly2014-11-231-1/+1

* Use containers of labeled search paths instead of individual membersChuck Atkins2014-11-121-27/+76
| | | | | | | 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 Atkins2014-11-111-40/+32
| | | | | | 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 Atkins2014-11-111-111/+134
| | | | | | | 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.
* strings: Remove redundant calls to std::string::c_str()Nils Gladitz2014-10-151-9/+9
| | | | | Replacements were detected and performed by the clang tool remove-cstr-calls on a linux build.
* Allow the Package Registry to be disabled (#14849)Daniele E. Domenichelli2014-05-121-0/+12
| | | | | | | | | | | | | | | | When a project is packaged for redistribution the local package registries should not be updated or consulted. They are for developers. Add variables to disable use of package registries globally: * CMAKE_EXPORT_NO_PACKAGE_REGISTRY that disables the export(PACKAGE) command * CMAKE_FIND_PACKAGE_NO_PACKAGE_REGISTRY that disables the User Package Registry in all the find_package calls. * CMAKE_FIND_PACKAGE_NO_SYSTEM_PACKAGE_REGISTRY that disables the System Package Registry in all the find_package calls. Update documentation and unit tests.
* Remove c_str calls when using stream APIs.Stephen Kelly2014-03-111-1/+1
| | | | | Use an ad-hoc clang tool for matching the calls which should be ported.
* Remove some c_str() calls.Stephen Kelly2014-03-111-55/+55
| | | | | | Use the clang RemoveCStrCalls tool to automatically migrate the code. This was only run on linux, so does not have any positive or negative effect on other platforms.
* strings: Remove cmStdString referencesBen Boeckel2014-03-081-1/+1
| | | | | | | | | | | Casts from std::string -> cmStdString were high on the list of things taking up time. Avoid such implicit casts across function calls by just using std::string everywhere. The comment that the symbol name is too long is no longer relevant since modern debuggers alias the templates anyways and the size is a non-issue since the underlying methods are generated since it's inherited.
* stringapi: Use strings for variable namesBen Boeckel2014-03-081-1/+2
| | | | Variable names are always generated by CMake and should never be NULL.
* FeatureSummary: Don't list transitive package dependenciesStephen Kelly2014-02-031-0/+6
| | | | | | | | | | | | | | Set a global property in the find_package implementation. Track and reset that property in the find_dependency macro. Read the property in FeatureSummary when determining whether to print output. This means that packages which are found only as dependencies are not listed by FeatureSummary, but if a project uses find_package elsewhere directly, then it will be listed by FeatureSummary.

* Drop compatibility with CMake < 2.4Brad King2013-10-231-96/+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.
* Drop builtin command documentationBrad King2013-10-161-316/+0
| | | | | Drop all GetTerseDocumentation and GetFullDocumentation methods from commands. The command documentation is now in Help/command/*.rst files.

* Revert "Add a way to exclude INTERFACE properties from exported targets."Stephen Kelly2013-02-131-21/+0
| | | | | | | | This reverts commit 2c3654c3de718fe822f8960063373774fc019494. 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.

* Add a way to exclude INTERFACE properties from exported targets.Stephen Kelly2013-01-311-0/+21
| | | | | | | | | | | | 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.
* exports: define a CMAKE_FIND_PACKAGE_NAME var set by find_package()Alex Neundorf2012-09-301-0/+2
| | | | | | | | | 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. Alex
* find_package: add support for a <package>_NOT_FOUND_MESSAGE variableAlex Neundorf2012-09-281-0/+10
| | | | | | | | If a config-file sets <package>_FOUND to FALSE, it can now give a reason using the variable <package>_NOT_FOUND_MESSAGE, which is used by cmFindPackage and FPHSA. Alex
* fix #13195: avoid multiple mentions of found packagesAlex Neundorf2012-05-061-32/+60
| | | | | | | Now before adding a package to the list of found or not-found packages, the package is remvoed from both lists before. Alex
* find_package: Fix components signature documentation (#13142)Brad King2012-04-191-3/+3
| | | | | Update the signature notation to show that "REQUIRED COMPONENTS ..." is allowed and that REQUIRED is an option on its own.
* find_package: Document <package>_FIND_* variables (#13142)Brad King2012-04-181-0/+23
| | | | | | | | When loading a find module or package config file the find_package command defines several variables to provide information about the caller's request. Previously this was documented only in the Modules/readme.txt file which is not distributed. Document the behavior explicitly in the main find_package documentation.
* find_package: add documentation for OPTIONAL_COMPONENTSAlex Neundorf2012-03-191-4/+9
| | | | | | | | This patch adds documentation for OPTIONAL_COMPONENTS to cmFindPackage.cxx, and also extends Modules/readme.txt significantly with regard to how components should be handled. Alex
* find_package: add OPTIONAL_COMPONENTS keywordAlex Neundorf2012-03-191-5/+39
| | | | | | | | Add an OPTIONAL_COMPONENTS keyword to find_package() so we can have a clear distinction between required and optional components. Don't allow a component to be both required and optional. Alex
* find_package: allow <pkg>Config.cmake to set <pkg>_FOUND to FALSEAlex Neundorf2012-03-131-4/+34
| | | | | | | | | | | 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

| | | | | | | | | | | | | | | | If in Config mode a configuration file could not be found, cmake printed an error, but did not actually stop processing. With SetFatalErrorOccured it does. Alex

* | find_package: Optionally warn when implicitly using Config modeBrad King2012-02-281-0/+41
| | | | | | | | | | | | | | | | | | | | | | Define variable CMAKE_FIND_PACKAGE_WARN_NO_MODULE for use by a project that wants to use an explicit mode in every call to find_package in order to generate more specific failure messages. Word the warning using the new CONFIG and MODULE mode keywords when the minimum required version of CMake is new enough to have them. Otherwise word the warning using the old NO_MODULE mode keyword.

* | find_package: Reject mixed use of MODULE- and CONFIG-only optionsBrad King2012-02-281-43/+37
| | | | | | | | | | Many options imply exclusive Config mode. The new MODULE option implies exclusive Module mode. Do not allow mixed combinations.
* | find_package: mention requested version number in error messageAlex Neundorf2012-02-281-2/+11
| | | | | | | | | | | | When neither a Find-module or a config file can be found print the required version so the user knows which version of the package to install.

| | | | | | | | | | The new mode differ from default mode in that that it doesn't fallback to config mode. The default mode stays unchanged.
* | find_package: improve error message when no Find module is presentAlex Neundorf2012-02-281-18/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
