* Order SYSTEM include directories after non-system directoriesEphi Sinowitz2018-04-231-1/+22
| | | | | | | An effect of the `-isystem` flag is to search the directory after those specified via `-I` flags. Make behavior more consistent on compilers that do not have any `-isystem` flag by explicitly moving system include directories to the end.

* | Revert "Remove CTestTestfile.cmake when BUILD_TESTING is OFF"Brad King2018-03-261-7/+4
|/ | | | | | | | | | | | | Revert commit v3.8.0-rc1~305^2 (Remove CTestTestfile.cmake when BUILD_TESTING is OFF, 2016-11-14) again. We reverted it once in commit v3.8.0-rc3~22^2 (Revert "Remove CTestTestfile.cmake when BUILD_TESTING is OFF", 2017-03-06) but it was accidentally restored by commit v3.11.0-rc1~387^2 (server: add "ctestInfo" request to get test info, 2017-10-25), perhaps due to conflict resolution during rebase. We cannot remove `CTestTestfile.cmake` when testing is off because it breaks projects that never enable testing but create their own `CTestTestfile.cmake` manually instead. Revert the change again and add a test case.
* Genex: Fix COMPILE_LANGUAGE in SYSTEM include directoriesBrad King2018-03-121-2/+2
| | | | | | | | | When evaluating `INTERFACE_SYSTEM_INCLUDE_DIRECTORIES`, or evaluating `INTERFACE_INCLUDE_DIRECTORIES` on an imported target, thread the compile language through to the generator expression evaluator so that it can support `$<COMPILE_LANGUAGE:...>`. Fixes: #17811
* Reduce raw string pointers usage.Pavel Solodovnikov2018-01-311-14/+14
| | | | | | | | | | * 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.
* cmLocalGenerator: change ImportedGeneratorTargets from vector to mapFrank Winklmeier2018-01-301-23/+5
| | | | | | | | For large number of targets significant amount of time is spent in cmLocalGenerator::FindGeneratorTargetToUse, which uses find_if on a vector to locate the given target. Using a map instead of vector for ImportedGeneratorTargets (as done for cmMakefile::ImportedTargets) provides a significant speedup (up to factor of 2).
* Reduce allocation of temporary values on heap.Pavel Solodovnikov2018-01-261-5/+5
| | | | | - Use `std::move` while inserting temporary results into vectors. - Change `push_back` to `emplace_back` where appropriate.

* CMake: enable setting default dir creation permissionsDomen Vrankar2017-11-081-0/+14
| | | | | | | | | Introduces CMAKE_DEFAULT_DIRECTORY_INSTALL_PERMISSIONS variable which enables the user to specify the default permissions for directory creation. This setting is then used to auto set the permissions on directories which are implicitly created by install() and file(INSTALL) commands such as CMAKE_INSTALL_PREFIX directories.

* | Replace cmArray{Begin,End,Size} by their standard counterpartsMatthias Maennich2017-10-231-2/+2
|/ | | | | | | | | | | std::{begin,end} are part of C++11, std::{cbegin,cend} are part of C++14 and an standard compliant implementation has been introduced within the 'cm' namespace: cm::{cbegin,cend}. std::size is only part of C++17, hence exposing a compliant implementation within namespace cm (cm::size). where possible, the standard implementations are reused.

* Performance: Add an index to Change cmLocalGenerator::GeneratorTargets.Aaron Orenstein2017-08-161-13/+14
| | | | | | | | | | | Add an index to Change cmLocalGenerator::GeneratorTargets for faster lookup by name. Also changed a bunch of uses of cmLocalGenerator::GetGeneratorTargets() to take const references instead of copying the vector. Represent generator targets as a map (name -> target) to make name lookups more efficient instead of looping through the entire vector to find the desired one.

| * | Android: Always add standard include directories lastBrad King2017-07-131-0/+14
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The logic added in commit v3.6.0-rc1~30^2 (Add a variable to specify language-wide system include directories, 2016-05-24) to use `CMAKE_<LANG>_STANDARD_INCLUDE_DIRECTORIES` incorrectly filters them by `CMAKE_<LANG>_IMPLICIT_INCLUDE_DIRECTORIES`. Rather than recognizing this, commit v3.8.0-rc1~60^2 (Android: Pass sysroot include directory explicitly, 2017-01-20) worked around the problem by incorrectly removing `/usr/include` from `CMAKE_<LANG>_IMPLICIT_INCLUDE_DIRECTORIES` so it worked in `CMAKE_<LANG>_STANDARD_INCLUDE_DIRECTORIES`. By not filtering out `/usr/include` from user-specified include directories, we allow the code include_directories(${CMAKE_SYSROOT}/usr/include) to place the include directory too early on the command line. Fix support for standard include directories to not be filtered by implicit include directories, and do not remove `/usr/include` from the list of implicit include directories for Android builds. Add a test case to verify that an explicit `/usr/include` is ignored in favor of the standard directory at the end. Fixes: #17059

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When `<LANG>_STANDARD` is not set we will not add any language standard flags. If `<LANG>_EXTENSIONS` is not OFF then our default is supposed to be ON. In order to support compilers that do not enable their extensions by default, check a `CMAKE_<LANG>_EXTENSION_COMPILE_OPTION` variable for an extensions flag to use without any language standard.

* | cmLocalGenerator: Add a hook for compiler flags used at link timeBrad King2017-05-011-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | When using a compiler to drive linking we add compiler flags from `CMAKE_<LANG>_FLAGS` in case they affect the way the compiler invokes the linker, but we don't add flags from other places that are meant only for compiling sources. Rather than calling the `AddLanguageFlags` method (which is used to add flags for compiling sources) directly, add an intermediate method that is used when adding the flags for linking. This will give us a way to add language-specific compiler flags needed when driving the linker in the same place on the command line as other compiler flags go.
* | Features: Refactor <LANG>_STANDARD updateBrad King2017-05-011-8/+25
|/ | | | | | | | | In order to support generator expressions in target COMPILE_FEATURES we apply them at generate time. Move this step to the beginning of generation instead of doing it on demand while collecting flags. This avoids repeating the process unnecessarily, and will then allow `cmLocalGenerator::AddCompilerRequirementFlag` to be used any time during generation.
