1VS_STARTUP_PROJECT 2------------------ 3 4.. versionadded:: 3.6 5 6Specify the default startup project in a Visual Studio solution. 7 8The :ref:`Visual Studio Generators` create a ``.sln`` file for each directory 9whose ``CMakeLists.txt`` file calls the :command:`project` command. Set this 10property in the same directory as a :command:`project` command call (e.g. in 11the top-level ``CMakeLists.txt`` file) to specify the default startup project 12for the corresponding solution file. 13 14The property must be set to the name of an existing target. This 15will cause that project to be listed first in the generated solution 16file causing Visual Studio to make it the startup project if the 17solution has never been opened before. 18 19If this property is not specified, then the ``ALL_BUILD`` project 20will be the default. 21
