.. versionadded:: 3.6
Specify the default startup project in a Visual Studio solution.
The :ref:Visual Studio Generators create a .sln file for each directory
whose CMakeLists.txt file calls the :command:project command. Set this
property in the same directory as a :command:project command call (e.g. in
the top-level CMakeLists.txt file) to specify the default startup project
for the corresponding solution file.
The property must be set to the name of an existing target. This will cause that project to be listed first in the generated solution file causing Visual Studio to make it the startup project if the solution has never been opened before.
If this property is not specified, then the ALL_BUILD project
will be the default.
