Run CMake while closing Visual Studio Solution
#!/usr/bin/env ruby
#
# Script that makes updating Visual Studio Solutions from CMakeLists'
# easier, by closing the solution via COM and automatically re-running
# CMake in the corresponding build directory, then reopening and
# building the solution.
#
# Simply run 'cmakevs.rb' from the command line, and it will find an
# instance of Visual Studio and detect the open solution and re-run
# CMake.

# b - a cmake convinience tool
#
# Runs build commands (e.g. cmake --build ., ctest, etc) in the

# build directory:

# c:\source\git\repo> b
