+
+This page is supposed to be a reference for the options in the `cmake.toml` file. If you think anything is missing or unclear, please [edit this page](https://github.com/build-cpp/cmkr/edit/main/docs/cmake-toml.md) or open an [issue](https://github.com/build-cpp/cmkr/issues).
+
+See the [examples](/examples) section for more real-world examples.

+## CMake configuration
+
+```toml
+[cmake]
+version = "3.15"
+cmkr-include = "cmkr.cmake"
+```
+
+## Project configuration
+
+```toml
+[project]
+name = "myproject"
+version = "1.0.0"
+description = "Description of the project"
+languages = ["C", "CXX"]
+cmake-before = """
+message(STATUS "CMake injected before the project() call")

+include-before = ["cmake/before-project.cmake"]
+include-after = ["cmake/after-project.cmake"]

+
+## Conditions
+
+```toml

+## Vcpkg
+
+```toml

+url = "https://github.com/microsoft/vcpkg/archive/refs/tags/2021.05.12.tar.gz"
+packages = ["fmt", "zlib"]
+```
+
+The vcpkg `version` will automatically generate the `url` from the official repository. For a custom registry you can specify your own `url` (and omit the `version`).
+
+## Packages
+
+```toml
+[find-package]

+components = ["mycomponent"]

+
+**Note**: The `[fetch-content]` feature is unpolished and will likely change in a future release.
+

+## Tests and installation (unfinished)
+

+
+As you can see in the example above you can use `**.ext` to glob recursively and `*.ext` to glob non-recursively. This **does not** generate `file(GLOB ...)` commands, but instead globs when cmkr is run. Files are sorted to give deterministic results regardless of the platform used.
