+# vcpkg_cmake_get_vars
+
+Runs a cmake configure with a dummy project to extract certain cmake variables
+
+## Usage
+```cmake
+vcpkg_cmake_get_vars(<out-var>)
+```
+
+`vcpkg_cmake_get_vars(<out-var>)` sets `<out-var>` to
+a path to a generated CMake file, with the detected `CMAKE_*` variables
+re-exported as `VCPKG_DETECTED_CMAKE_*`.
+
+## Notes
+Avoid usage in portfiles.
+
+All calls to `vcpkg_cmake_get_vars` will result in the same output file;
+the output file is not generated multiple times.
+
+### Basic Usage
