Detecting when the cache is dirty (#284 )

* Check that the cache working directory is clean * cpm_check_working_dir_is_clean for non git repo will not terminate cmake * sileneced check for git repo, in case of error * style(CPM.cmake): fixed indentation for ERROR_QUIET * refactor(CPM.cmake): added logic to handle a cache folder inside a (not correlated) git repo this is accomplished by checking if we are in the directory where .git lives * style(CPM.cmake): stray tab to spaces * test(dirty-cache-check): added unit test to check cpm_check_working_dir_is_clean the test creates a file in a folder and then uses git to create a repo in that folder, to check various conditions * Update test/unit/dirty-cache-check.cmake added user.name and user.email to comply with test machine where git is not completely configured Co-authored-by: Lars Melchior <TheLartians@users.noreply.github.com> * feat(cpm_check_working_dir_is_clean): now it takes a git tag (works with hashes too) to check for uncommitted and commited changes * refactor(cpm_check_working_dir_is_clean): early return for the most common case of uncommited changes in a repo * refactor(cpm_check_git_working_dir_is_clean): removed edgecase detection (a non-git folder in an unrelated git repo) now the contract is that com_check_git_working_dir_is_clean is given the base folder of a git repo Co-authored-by: Andrew Gribble <ag131012@renishaw.com> Co-authored-by: Lars Melchior <TheLartians@users.noreply.github.com>

 If `GIT_TAG` hasn't been explicitly specified it defaults to `v(VERSION)`, a common convention for git projects.
-On the other hand, if `VERSION` hasn't been explicitly specified, CPM can automatically identify the version from the git tag in some common cases. 
-`GIT_TAG` can also be set to a specific commit or a branch name such as `master` to always download the most recent version.
-The optional argument `FIND_PACKAGE_ARGUMENTS` can be specified to a string of parameters that will be passed to `find_package` if enabled (see below).
+On the other hand, if `VERSION` hasn't been explicitly specified, CPM can automatically identify the version from the git tag in some common cases.
+`GIT_TAG` can also be set to a specific commit or a branch name such as `master`, however this isn't recommended, as such packages will only be updated when the cache is cleared.

-After calling `CPMAddPackage` or `CPMFindPackage`, the following variables are defined in the local scope, where `<dependency>` is the name of the dependency.
+If an additional optional parameter `EXCLUDE_FROM_ALL` is set to a truthy value, then any targets defined inside the dependency won't be built by default. See the [CMake docs](https://cmake.org/cmake/help/latest/prop_tgt/EXCLUDE_FROM_ALL.html) for details.
+
+A single-argument compact syntax is also supported:
+
+```cmake
+# A git package from a given uri with a version
+CPMAddPackage("uri@version")
+# A git package from a given uri with a git tag or commit hash
+CPMAddPackage("uri#tag")
+# A git package with both version and tag provided
+CPMAddPackage("uri@version#tag")
+```
+
+In the shorthand syntax if the URI is of the form `gh:user/name`, it is interpreted as GitHub URI and converted to `https://github.com/user/name.git`. If the URI is of the form `gl:user/name`, it is interpreted as a [GitLab](https://gitlab.com/explore/) URI and converted to `https://gitlab.com/user/name.git`. If the URI is of the form `bb:user/name`, it is interpreted as a [Bitbucket](https://bitbucket.org/) URI and converted to `https://bitbucket.org/user/name.git`. Otherwise the URI used verbatim as a git URL. All packages added using the shorthand syntax will be added using the [EXCLUDE_FROM_ALL](https://cmake.org/cmake/help/latest/prop_tgt/EXCLUDE_FROM_ALL.html) flag.
+
+The single-argument syntax also works for URLs:
+
+```cmake
+# An archive package from a given url. The version is inferred
+CPMAddPackage("https://example.com/my-package-1.2.3.zip")
+# An archive package from a given url with an MD5 hash provided
+CPMAddPackage("https://example.com/my-package-1.2.3.zip#MD5=68e20f674a48be38d60e129f600faf7d")
+# An archive package from a given url. The version is explicitly given
+CPMAddPackage("https://example.com/my-package.zip@1.2.3")
+```
+
+After calling `CPMAddPackage`, the following variables are defined in the local scope, where `<dependency>` is the name of the dependency.

 - `<dependency>_SOURCE_DIR` is the path to the source of the dependency.
 - `<dependency>_BINARY_DIR` is the path to the build directory of the dependency.
 - `<dependency>_ADDED` is set to `YES` if the dependency has not been added before, otherwise it is set to `NO`.

-The difference between `CPMFindPackage` and `CPMAddPackage` is that `CPMFindPackage` will try to find a local dependency via CMake's `find_package` and fallback to `CPMAddPackage` if the dependency is not found.
-This behaviour can be also modified globally via [CPM options](#options).
+For using CPM.cmake projects with external package managers, such as conan or vcpkg, setting the variable [`CPM_USE_LOCAL_PACKAGES`](#options) will make CPM.cmake try to add a package through `find_package` first, and add it from source if it doesn't succeed.

 ## Limitations

 - **No pre-built binaries** For every new build directory, all dependencies are initially downloaded and built from scratch. To avoid extra downloads it is recommend to set the [`CPM_SOURCE_CACHE`](#CPM_SOURCE_CACHE) environmental variable. Using a caching compiler such as [ccache](https://github.com/TheLartians/Ccache.cmake) can drastically reduce build time.
- **Dependent on good CMakeLists** Many libraries do not have CMakeLists that work well for subprojects. Luckily this is slowly changing, however, until then, some manual configuration may be required (see the snippets [below](#snippets) for examples). For best practices on preparing projects for CPM, see the [wiki](https://github.com/TheLartians/CPM.cmake/wiki/Preparing-projects-for-CPM.cmake). 
- **First version used** In diamond-shaped dependency graphs (e.g. `A` depends on `C`@1.1 and `B`, which itself depends on `C`@1.2 the first added dependency will be used (in this case `C`@1.1). In this case, B requires a newer version of `C` than `A`, so CPM will emit a warning. This can be easily resolved by adding a new version of the dependency in the outermost project, or by introducing a [package lock file](https://github.com/TheLartians/CPM.cmake/wiki/Package-lock).

This can be easily resolved by adding a new version of the dependency in the outermost project, or by introducing a [package lock file](#package-lock).

 For projects with more complex needs and where an extra setup step doesn't matter, it may be worth to check out an external C++ package manager such as [vcpkg](https://github.com/microsoft/vcpkg), [conan](https://conan.io) or [hunter](https://github.com/ruslo/hunter).
 Dependencies added with `CPMFindPackage` should work with external package managers.
 Additionally, the option [`CPM_USE_LOCAL_PACKAGES`](#cpmuselocalpackages) will enable `find_package` for all CPM dependencies.

+## Comparison to FindPackage
+
+The usual way to add libraries in CMake projects is to call `find_package(<PackageName>)` and to link against libraries defined in a `<PackageName>_LIBRARIES` variable.
+While simple, this may lead to unpredictable builds, as it requires the library to be installed on the system and it is unclear which version of the library has been added.
+Additionally, it is difficult to cross-compile projects (e.g. for mobile), as the dependencies will need to be rebuilt manually for each targeted architecture.
+
+CPM.cmake allows dependencies to be unambiguously defined and builds them from source.
+Note that the behaviour differs from `find_package`, as variables exported to the parent scope (such as  `<PackageName>_LIBRARIES`) will not be visible after adding a package using CPM.cmake.
+The behaviour can be [achieved manually](https://github.com/cpm-cmake/CPM.cmake/issues/132#issuecomment-644955140), if required.
+
+## Comparison to pure FetchContent / ExternalProject
+
+CPM.cmake is a wrapper for CMake's FetchContent module and adds a number of features that turn it into a useful dependency manager.
+The most notable features are:
+
+- A simpler to use API
+- Version checking: CPM.cmake will check the version number of any added dependency and emit a warning if another dependency requires a more recent version.
+- Offline builds: CPM.cmake will override CMake's download and update commands, which allows new builds to be configured while offline if all dependencies [are available locally](#cpm_source_cache).
+- Automatic shallow clone: if a version tag (e.g. `v2.2.0`) is provided and `CPM_SOURCE_CACHE` is used, CPM.cmake will perform a shallow clone of the dependency, which should be significantly faster while using less storage than a full clone.
+- Overridable: all `CPMAddPackage` can be configured to use `find_package` by setting a [CMake flag](#cpm_use_local_packages), making it easy to integrate into projects that may require local versioning through the system's package manager.
+- [Package lock files](#package-lock) for easier transitive dependency management.
+- Dependencies can be overridden [per-build](#local-package-override) using CMake CLI parameters.
+
+ExternalProject works similarly as FetchContent, however waits with adding dependencies until build time.
+This has a quite a few disadvantages, especially as it makes using custom toolchains / cross-compiling very difficult and can lead to problems with nested dependencies.

+
+## Local package override
+
+Library developers are often in the situation where they work on a locally checked out dependency at the same time as on a consumer project.
+It is possible to override the consumer's dependency with the version by supplying the CMake option `CPM_<dependency name>_SOURCE` set to the absolute path of the local library.
+For example, to use the local version of the dependency `Dep` at the path `/path/to/dep`, the consumer can be built with the following command.
+

+This will list all CPM.cmake dependencies and can be used to update dependencies without modifying the original `CMakeLists.txt`.
+To use a package lock, add the following line directly after including CPM.cmake.
+
+```cmake
+CPMUsePackageLock(package-lock.cmake)
+```
+
+To create or update the package lock file, build the `cpm-update-package-lock` target.
+
+```bash
+cmake -Bbuild
+cmake --build build --target cpm-update-package-lock
+```
+
+See the [wiki](https://github.com/cpm-cmake/CPM.cmake/wiki/Package-lock) for more info.
+
+## Built with CPM.cmake
+
+Some amazing projects that are built using the CPM.cmake package manager.
+If you know others, feel free to add them here through a PR.

Andrea Barbadoro	f552da96bd	Detecting when the cache is dirty (#284 ) * Check that the cache working directory is clean * cpm_check_working_dir_is_clean for non git repo will not terminate cmake * sileneced check for git repo, in case of error * style(CPM.cmake): fixed indentation for ERROR_QUIET * refactor(CPM.cmake): added logic to handle a cache folder inside a (not correlated) git repo this is accomplished by checking if we are in the directory where .git lives * style(CPM.cmake): stray tab to spaces * test(dirty-cache-check): added unit test to check cpm_check_working_dir_is_clean the test creates a file in a folder and then uses git to create a repo in that folder, to check various conditions * Update test/unit/dirty-cache-check.cmake added user.name and user.email to comply with test machine where git is not completely configured Co-authored-by: Lars Melchior <TheLartians@users.noreply.github.com> * feat(cpm_check_working_dir_is_clean): now it takes a git tag (works with hashes too) to check for uncommitted and commited changes * refactor(cpm_check_working_dir_is_clean): early return for the most common case of uncommited changes in a repo * refactor(cpm_check_git_working_dir_is_clean): removed edgecase detection (a non-git folder in an unrelated git repo) now the contract is that com_check_git_working_dir_is_clean is given the base folder of a git repo Co-authored-by: Andrew Gribble <ag131012@renishaw.com> Co-authored-by: Lars Melchior <TheLartians@users.noreply.github.com>	2021-09-15 11:38:49 +02:00
