+CMake
+=====
+
+Initializes build directories for [CMake][1].
+
+### Usage
+
+```sh
+# In the root directory of a CMake project:
+$ mb
+# Or with additional flags:
+$ mb -DSOME_EXTRA_FLAGS="foo"
+```
+
+### Options
+
+```sh
+# Set the install prefix.
+zstyle ':prezto:module:cmake' install-prefix '/usr'
+
+# Set the build prefix.
+zstyle ':prezto:module:cmake' build-prefix '_build'
+
+# Set the build profiles.
+zstyle ':prezto:module:cmake' profiles 'Debug' 'Release'
+
+# Whether to support clang as well.
+zstyle ':prezto:module:cmake' support-clang 'yes'
+```
+
+### Aliases
+
+* `mb` initialize build directories.
