I have 2 executable projects each of which depends from 2 libraries in one solution (root CMakeLists.txt). Build is ok and as result I have 2 libraries and 2 executable. But when I try to open root CMakeLists.txt in Qt creator instead 4 projects (src1, src2, subproject1, subproject2) & CMakeLists.txt in the root as result I have only 1 project with name "Project" which includes my 4 projects in "Project" container like this is include folders.

Also I cannot select project for run (Set project "Project" as Active Project) since this is only one project. After run from Qt the MainProject1 was run.

StackOverflow and google propoused to use add_subdirectory for this but this does not work. In my CMakeLists's for make depends and several projects I already had used add_subdirectory.

Qt version: 5.7.0.
Qt Creator version: 4.0.2.
Ubuntu

Please help me for fix this. Thanks in advance.

Project structure & manual build & results: Succeed

Project structure:

    src2                    (executable which depends from subproject1 and subproject2)

Build is ok.

Run project

MainProject1 was run. Cannot select project for run since Qt Creator perceives root CMakeLists as if it's only one project.
