"current executable" target generates wrong string

The new beta version seems to have problems to translate the "current executable" into the proper string to be given to CMake.

Status:

• The project is properly configured: using either the terminal or QtCreator.
• The list of targets is properly populated in QtCreator/Projects/Build Settings/Build Steps/Targets
• If I choose a specific target and I compile, it works as expected:

  Build:  cmake.exe --build . --target api
  # After clicking in build 
  15:51:54: Starting: "C:\Program Files\CMake\bin\cmake.exe" --build . --target api
  ... OK
  

• If I choose "Current executable", this happens:

  Build:  cmake.exe --build . --target "<Current executable>"
  15:53:59: Starting: "C:\Program Files\CMake\bin\cmake.exe" --build . --target C:/dev/explore/export_api/tests///::///testExport
  ninja: error: unknown target 'C:/dev/explore/export_api/tests/::/testExport'
  

Note that this was working properly in QtCreator 4.9.
