[CMake] How to manage dependencies between projects in Visual Studio

[Luca Gherardi]

Actually a solution for this is using add_subdirectory().

 

The problem is that I use two out-of-source build directories, one for
building A and one for B.

 

If I use some directory the files generated during the compilation of A will
be stored:

- in the out-of-source build folder of solution A when the compilation is
launched from the solution A, 

- in the out-of-source build folder of solution B when the compilation is
launched from the solution B, 

 

In this way there is a duplication of files, which I would like to avoid.

 

A solution could be use the “binary_dir” option and specify that the project
A has to be built in the out-of-source build folder of solution A also when
the compilation is launched from B.

 

 

This would be the folder organization:

 

Root

- A

  - CMakeLists.txt

 - src

- B

  - CMakeLists.txt

 - src

- BUILD_A

- BUILD_B

 

And the CMakeLists of be would contain the following line:

 

Add_subdirectory(ABSOLUT_PATH_TO_A   BUILD_A)

 

 

Does it make sense?

 

Thanks!

Sorry, I've never used either functionality myself. I just wanted to point
out what exists.

Hi Peter,

 

I tried to use the include_external_msproject(PROJECT_NAME PATH_TO_VCXPROJ)

 

The project is included in the solution, however when I try to build the
solution VS returns the following error:

 

“The operation could not be completed. The parameter is incorrect”

 

No other information.

Any idea?

 

Thanks,

Luca

Hi Luca.

You could look into the CMake command include_external_msproject(), or into
the ExternalProject module.

I’m working with Visual Studio and I need to create the CMakeLists files for
the following scenario.

 

I have a project A, which contains the sources for a library.

This project has its own CMakeLists and generates a lib (add_library).

 

I have a second project B, which contains the sources from an executable and
uses the library generated by A.

I would like to setup its CMakeLists in such a way that:

 

-        The Visual Studio solution generated from the CMakeLists of B
includes the projects for A and B

-        The project A should be just a link to the project generated with
the CMakeLists of A. In other words I would like to avoid duplications of
compilation files. I would like that the file generated for A by a
compilation started from the solution of A were stored in the same path of
the file generated for A by a compilation started from the solution of B.

 

Is that possible?

I know it is possible to do it with visual studio, but I don’t know how to
do it with CMake.

 

Thanks in advance.
