gtest not building properly when a second main is present in the project [BUG]

[riera90]

Description
When compiling and executing a gtest, and a second main is added in the / path of the project, this main is build under the name of the gtest and executed

Additional context
the name of the second main is not important, in this case is testfile.cpp
