Conan

--------

- BugFix: Fixed missing dependencies in ``AutoToolsBuildEnvironment``
- BugFix: Escaping single quotes in html graph of ``conan info --graph=file.html``
- BugFix: Fixed loading of auth plugins in conan_server
- BugFix: Fixed ``visual_studio`` generator creating XML with dots.

-------------------------------

- Feature: ``conan info --graph`` or ``--graph=file.html`` will generate a dependency graph representation in dot or html formats.
- Feature: Added better support and tests for Solaris Sparc.
- Feature: custom authenticators are now possible in ``conan_server`` with plugins.
- Feature: extended ``conan info`` command with path information and filter by packages.
- Feature: enabled conditional package binaries removal with ``conan remove`` with query syntax
- Feature: enabled generation and validation of manifests from ``test_package``.
- Feature: allowing ``options`` definitions in profiles
- Feature: new ``RunEnvironment`` helper, that makes easier to run binaries from dependent packages
- Feature: new ``virtualrunenv`` generator that activates environment variable for execution of binaries from installed packages, without requiring ``imports`` of shared libraries.
- Feature: adding new version modes for ABI compatibility definition in ``package_id()``.
- Feature: Extended ``conan new`` command with new option for ``exports_sources`` example recipe.
- Feature: ``CMake`` helper defining parallel builds for gcc-like compilers via ``--jN``, allowing user definition with environment variable and in conan.conf.
- Feature: ``conan profile`` command now show profiles in alphabetical order.
- Feature: extended ``visual_studio`` generator with more information and binary paths for execution with DLLs paths.
- Feature: Allowing relative paths with $PROFILE_DIR place holder in ``profiles``
- Fix: using only file checksums to decide for modified recipe in remote, for possible concurrent builds & uploads.
- Fix: Improved ``--build`` modes management, with better checks and allowing multiple definitions and mixtures of conditions
- Fix: Replaced warning for non-matching OS to one message stating the cross-build
- Fix: local ``conan source`` command (working in user folder) now properly executes the equivalent of ``exports`` functionality
- Fix: Setting command line arguments to cmake command as CMake flags, while using the TARGETS approach. Otherwise, arch flags like -m32 -m64 for gcc were not applied.
- BugFix: fixed ``conan imports`` destination folder issue.
- BugFix: Allowing environment variables with spaces
- BugFix: fix for CMake with targets usage of multiple flags.
- BugFix: Fixed crash of ``cmake_multi`` generator for "multi-config" packages.

--------

- Fix: Added opt-out for ``CMAKE_SYSTEM_NAME`` automatically added when cross-building, causing users
providing their own cross-build to fail
- BugFix: Corrected usage of ``CONAN_CFLAGS`` instead of ``CONAN_C_FLAGS`` in cmake targets

- Fix: Regression of `visual_studio`generator using `%(ExecutablePath)` instead of `$(ExecutablePath)`
- Fix: Regression for `--build=outdated --build=Pkg` install pattern

- Fix: Disabled the use of cached settings and options from installed `conaninfo.txt`
- Fix: Revert the use of quotes in `cmake` generator for flags.
- Fix: Allow comments in artifacts.properties
- Fix: Added missing commit for CMake new helpers

- Feature: Largely improved management of **environment variables**, declaration in `package_info()`,
definition in profiles, in command line, per package, propagation to consumers.
- Feature: New build helpers `AutotoolsBuildEnvironment`, `VisualStudioBuildEnvironment`, which
deprecate `ConfigureEnvironment`, with much better usage of environment variables
- Feature: New `virtualbuildenv` generator that will generate a composable environment with build
information from installed dependencies.
- Feature: New `build_id()` recipe method that allows to define logic to build once, and package
multiple times without building. E.g.: build once both debug and release artifacts, then package
separately.
- Feature: **Multi-config packages**. Now packages can provide multi-configuration packages, like
both debug/release artifacts in the same package, with `self.cpp_info.debug.libs = [...]` syntax.
Not restricted to debug/release, can be used for other purposes.
- Feature: new `conan config` command to manage, edit, display `conan.conf` entries
- Feature: Improvements to `CMake` build helper, now it has `configure()` and `build()` methods
for common operations.
- Feature: Improvements to `SystemPackageTool` with detection of installed packages, improved
implementation, installation of multi-name packages.
- Feature: Unzip with `tools.unzip` maintaining permissions (Linux, OSX)
- Feature: `conan info` command now allows profiles too
- Feature: new tools `unix_path()`, `escape_windows_cmd()`, `run_in_windows_bash()`, useful
for autotools projects in Win/MinGW/Msys
- Feature: new context manager `tools.chdir`, to temporarily change directory.
- Feature: CMake using `CMAKE_SYSTEM_NAME` for cross-compiling.
- Feature: Artifactory build-info extraction from traces
- Feature: Attach custom headers to artifacts uploads with an `artifacts.properties` file.
- Feature: allow and copy symlinks while `conan export`
- Fix: removing quotes in some cmake variables that were generating incorrect builds
- Fix: providing better error messages for non existing binaries, with links to the docs
- Fix: improved error messages if `tools.patch` failed
- Fix: adding `resdirs` to `cpp_info` propagated information, and cmake variables, for directories
containing resources and other data.
- Fix: printing error messages if a `--build` policy doesn't match any package
- Fix: managing VS2017 by `tools`. Still the manual definition of `vs150comntools` required.
- Bug fix: crashes when not supported characters were dumped to terminal by logger
- Bug fix: wrong executable path in Visual Studio generator

**NOTE**: It is important that you upgrade at least to 0.19.3 version if you are using remotes with packages that might be created with 0.20.0 version.
