[c++] Using CMake to generate Visual Studio C++ project files

I am working on an open source C++ project, for code that compiles on Linux and Windows. I use CMake to build the code on Linux. For ease of development setup and political reasons, I must stick to Visual Studio project files/editor on Windows (I can't switch to Code::Blocks, for example). I see instructions to generate Visual Studio files using CMake, as here.

Have you used CMake to generate Visual Studio files before? How has been your experience? Suppose I want to add a new file to my project. What is the workflow for this?

As Alex says, it works very well. The only tricky part is to remember to make any changes in the cmake files, rather than from within Visual Studio. So on all platforms, the workflow is similar to if you'd used plain old makefiles.

But it's fairly easy to work with, and I've had no issues with cmake generating invalid files or anything like that, so I wouldn't worry too much.

Not sure if it's directly related to the question, but I was looking for an answer for how to generate *.sln from cmake projects I've discovered that one can use something like this:

cmake -G "Visual Studio 10"

The example generates needed VS 2010 files from an input CMakeLists.txt file

CMake can generate really nice Visual Studio .projs/.slns, but there is always the problem with the need to modify the .cmake files rather than .proj/.sln. As it is now, we are dealing with it as follows:

1. All source files go to /src and files visible in Visual Studio are just "links" to them defined in .filter.
2. Programmer adds/deletes files remembering to work on the defined /src directory, not the default project's one.
3. When he's done, he run a script that "refreshes" the respective .cmake files.
4. He checks if the code can be built in the recreated environment.
5. He commits the code.

At first we were a little afraid of how it will turn out, but the workflow works really well and with nice diff visible before each commit, everyone can easily see if his changes were correctly mapped in .cmake files.

One more important thing to know about is the lack of support (afaik) for "Solution Configurations" in CMake. As it stands, you have to generate two directories with projects/solutions - one for each build type (debug, release, etc.). There is no direct support for more sophisticated features - in other words: switching between configurations won't give you what you might expect.

We moved our department's build chain to CMake, and we had a few internal roadbumps since other departments where using our project files and where accustomed to just importing them into their solutions. We also had some complaints about CMake not being fully integrated into the Visual Studio project/solution manager, so files had to be added manually to CMakeLists.txt; this was a major break in the workflow people were used to.

But in general, it was a quite smooth transition. We're very happy since we don't have to deal with project files anymore.

The concrete workflow for adding a new file to a project is really simple:

1. Create the file, make sure it is in the correct place.
2. Add the file to CMakeLists.txt.
3. Build.

CMake 2.6 automatically reruns itself if any CMakeLists.txt files have changed (and (semi-)automatically reloads the solution/projects).

Remember that if you're doing out-of-source builds, you need to be careful not to create the source file in the build directory (since Visual Studio only knows about the build directory).

CMake produces Visual Studio Projects and Solutions seamlessly. You can even produce projects/solutions for different Visual Studio versions without making any changes to the CMake files.

Adding and removing source files is just a matter of modifying the CMakeLists.txt which has the list of source files and regenerating the projects/solutions. There is even a globbing function to find all the sources in a directory (though it should be used with caution).

The following link explains CMake and Visual Studio specific behavior very well.

CMake and Visual Studio

I've started my own project, called syncProj. Documentation / download links from here:

If you're planning to use Visual studio for development, and currently only C++ is supported.

Main advantage compared to other make systems is that you can actually debug your script, as it's C# based.

If you're not familiar with syncProj, you can just convert your solution / project to .cs script, and continue further development from that point on.

In cmake you will need to write everything from scratch.

Lots of great answers here but they might be superseded by this CMake support in Visual Studio (Oct 5 2016)
