* clang-tidy: modernize-use-autoRegina Pfeifer2019-09-101-2/+1
| | | | | | Set the MinTypeNameLength option to an impossibly high value in order to limit the diagnostics to iterators. Leave new expressions and cast expressions for later.
* Add per-lang variants of CMAKE_LINK_LIBRARY_{FILE_FLAG,SUFFIX}Alan W. Irwin2019-08-271-4/+14
| | | | | | | | | | Extend the change from commit 689be6235e (Generator: support per-language link library flag, 2019-08-08) to cover more link library command-line flag components. Allow compilers for different languages to use different values for these linking-related variables within the same build. Closes: #19631
* Source sweep: Replace cmExpandList with the shorter cmExpandedListSebastian Holtermann2019-08-231-10/+5
| | | | | | | | | | | | This replaces the code pattern ``` std::vector<std::string> args; cmExpandList(valueStr, args, ...) ``` with ``` std::vector<std::string> args = cmExpandedList(valueStr, ...) ```
* Source sweep: Use cmStrCat for string concatenationSebastian Holtermann2019-08-221-63/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is generated by a python script that uses regular expressions to search for string concatenation patterns of the kind ``` std::string str = <ARG0>; str += <ARG1>; str += <ARG2>; ... ``` and replaces them with a single `cmStrCat` call ``` std::string str = cmStrCat(<ARG0>, <ARG1>, <ARG2>, ...); ``` If any `<ARGX>` is itself a concatenated string of the kind ``` a + b + c + ...; ``` then `<ARGX>` is split into multiple arguments for the `cmStrCat` call. If there's a sequence of literals in the `<ARGX>`, then all literals in the sequence are concatenated and merged into a single literal argument for the `cmStrCat` call. Single character strings are converted to single char arguments for the `cmStrCat` call. `std::to_string(...)` wrappings are removed from `cmStrCat` arguments, because it supports numeric types as well as string types. `arg.substr(x)` arguments to `cmStrCat` are replaced with `cm::string_view(arg).substr(x)`

* Generator: support per-language link library flagSaleem Abdulrasool2019-08-091-2/+7
| | | | | | | | This enables the use of MSVC and Swift on Windows in a single project. MSVC uses no flag to indicate linked libraries while Swift uses `-l`. Add support for a language specific link library flag which takes precedence over the global `CMAKE_LINK_LIBRARY_FLAG` which preserves compatibility with earlier releases.
* clang-tidy: Enable performance-inefficient-string-concatenationSebastian Holtermann2019-08-051-1/+1
| | | | | | | Enables the clang-tidy test performance-inefficient-string-concatenation and replaces all inefficient string concatenations with `cmStrCat`. Closes: #19555
* Make CMAKE_LINK_LIBRARY_FILE_FLAG work like CMAKE_LINK_LIBRARY_FLAGBrad King2019-08-021-10/+0
| | | | | | | | | | | | | | | | | | The `CMAKE_LINK_LIBRARY_FILE_FLAG` variable is meant for linkers that want library file paths to be preceded by a flag. This is used only for OpenWatcom to add the `library` argument before library file paths. Refactor the approach to treat `CMAKE_LINK_LIBRARY_FILE_FLAG` as a command-line string fragment to add just before the library file path. This has two advantages: * `CMAKE_LINK_LIBRARY_FILE_FLAG` now works like `CMAKE_LINK_LIBRARY_FLAG`. * `CMAKE_LINK_LIBRARY_FILE_FLAG` can now be an attached flag whose value is the library file path. Technically this is a change in behavior, but this setting was created for internal use and should be rarely used outside of CMake itself. Fixes: #19541
* cmStringAlgorithms: Move string functions to the new cmStringAlgorithms.hSebastian Holtermann2019-07-291-1/+1
| | | | | This adds the `cmStringAlgorithms.h` header and moves all string functions from `cmAlgorithms.h` to `cmStringAlgorithms.h`.
* AIX: Create import library for executables with exportsBrad King2019-07-161-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On AIX, plugins meant to be loaded into executables via `dlopen` must be linked with access to a list of symbols exported from the executable in order to use them (when not using runtime linking). The AIX linker supports specifying this list as an "import file" passed on the command line either via the `-bI:...` option or (with a leading `#! .` line) as a normal input file like any other library file. The linker import file plays the same role on AIX as import libraries do on Windows. Teach CMake to enable its import library abstraction on AIX for executables with the `ENABLE_EXPORTS` target property set. Teach our internal `ExportImportList` script to optionally generate a leading `#! .` line at the top of the generated export/import list. Update our rule for linking an executable with exports to generate a public-facing "import library" implemented as an AIX linker import file. With this approach, our existing infrastructure for handling import libraries on Windows will now work for AIX linker import files too: * Plugins that link to their executable's symbols will be automatically linked using the import file on the command line. * The executable's import file will be (optionally) installed and exported for use in linking externally-built plugins. This will allow executables and their plugins to build even if we later turn off runtime linking. Issue: #19163
* Refactor checks for whether a target has an import libraryBrad King2019-07-121-15/+6
| | | | Use `HasImportLibrary` for such checks.

* RPATH: Add option for using $ORIGIN in build treePeter Wu2018-10-261-3/+26
| | | | | | | | | This makes binaries independent of the build directory by not embedding the build directory via RPATH. The tests are partially based on the existing RuntimePath test, but with the check moved into a POST_BUILD command such that it can be skipped when the platform lacks support. Fixes: #18413

* objlib: Allow other libraries to link to `OBJECT` libraries.Deniz Bahadir2018-03-011-0/+3
| | | | | | | | Note: This only allows `OBJECT` libraries to be on the right-hand side of `target_link_libraries` but still does not link its object-files to the target on the left-hand side. Issue: #14778
* Reduce raw string pointers usage.Pavel Solodovnikov2018-01-311-5/+6
| | | | | | | | | | * Change some functions to take `std::string` instead of `const char*` in the following classes: `cmMakeFile`, `cmake`, `cmCoreTryCompile`, `cmSystemTools`, `cmState`, `cmLocalGenerator` and a few others. * Greatly reduce using of `const char*` overloads for `cmSystemTools::MakeDirectory` and `cmSystemTools::RelativePath`. * Remove many redundant `c_str()` conversions throughout the code.
* Reduce allocation of temporary values on heap.Pavel Solodovnikov2018-01-261-17/+17
| | | | | - Use `std::move` while inserting temporary results into vectors. - Change `push_back` to `emplace_back` where appropriate.
* cmComputeLinkInformation: Better RPATH detection for versioned libraries.Byoungchan Lee2018-01-221-5/+3
| | | | | | | | | | | Some libraries uses the non-conventional SONAME scheme like `libssl.so.1.1` or `libboost_system.so.1.64.0`, but CMake didn't count on such versioned libraries. This commit modify regular expressions to match relaxed format of shared library name for determining various linker options, especially `RPATH`. Note that support for one component has been available since v2.8.12. Fixes: #15938

| | | | | | | | | Add `CMAKE_SYSROOT_COMPILE` and `CMAKE_SYSROOT_LINK` variables to as operation-specific alternatives to `CMAKE_SYSROOT`. This will be useful for Android NDKs that compile and link with different sysroot values (e.g. `r14` with unified headers). Co-Author: Florent Castelli <florent.castelli@gmail.com>
* Replace boolean `implib` parameters with enumGregor Jasny2017-04-201-4/+16
| | | | | Named enumeration values are much clearer at call sites and add more type safety.
* Allow imported INTERFACE libraries to specify a link library nameBrad King2016-11-091-0/+6
| | | | | | | | | | | | | | | Add an `IMPORTED_LIBNAME[_<CONFIG>]` target property to specify a library name to be placed on the link line in place of an interface library since it has no library file of its own. Restrict use of the property to imported `INTERFACE` libraries. This will be particularly useful for find modules that need to provide imported libraries from system SDKs where the full path to the library file is not known. Now such find modules will be able to provide an imported interface library and set `IMPORTED_LIBNAME` to refer to the SDK library by name. Issue: #15267

| | | | | | Users may need to add custom `RPATH` entries to be able to run binaries from their build tree without setting `LD_LIBRARY_PATH`. Provide a way to do this that does not affect the install-tree `RPATH`.
* 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.
