feat(cmake): Added CMake package

Addon changes:
- Added share directory to install script to fix CMAKE_ROOT not found
  issue.
- Added a simple CPP Hello World program for CMake usage.

Caution:
- Need to test Powershell script.

+  cmake: CMake is a cross-platform, open-source build system generator
+---
+
+To update or switch versions, run `webi cmake@stable` (or `@v2`, `@beta`,
+etc).
+
+### Files
+
+These are the files / directories that are created and/or modified with this
+install:
+
+```text
+~/.config/envman/PATH.env
+~/.local/bin/cmake
+~/.local/opt/cmake
+```
+To get the cmake version:
+
+```sh
+cmake --version
+```
+
+### Hello World with CMake:
+
+Lets create a hello world program in C++ and build it with CMake.
+
+- Start by creating a project directory
+
+```sh
+mkdir my-project && cd my-project
+```
+
+- Create a Hello World C++ file named hello-world.cpp
+
+```cpp
+#include <iostream>
+
+int main(int argc, char** argv) {
+	std::cout << "Hello World!" << std::endl;
+	return 0;
+}
+```
+
+- Now we create a CMakeLists.txt to compile our cpp file.
+
+```cmake
+project{hello-world}
+cmake_minimum_required(VERSION 3.10)
+
+add_executable(hello-world hello-world.cpp)
+
+```
+
+- Lets create a build directory and build the binary
+
+```sh
+mkdir build
+cd build
+cmake ..
+make
+```
+
+- Once we build the binary we can execute it via:
+
+```sh
+./hello-world
+```
