C++ units tests are not running when building the wheels

[nosmokingsurfer]

to run tests during build can simply build all targets with turned on tests. need execute the following commands in build directory:

cmake .. -DBUILD_TESTING=ON
make all
make test

The result should be somewhat like this:

Running tests...
Test project .../mrob/build
    Start 1: test_SE3
1/2 Test #1: test_SE3 .........................   Passed    0.01 sec
    Start 2: test_SE3cov
2/2 Test #2: test_SE3cov ......................   Passed    0.02 sec

100% tests passed, 0 tests failed out of 2

Total Test time (real) =   0.03 sec

i guess during cmake lists refactoring this part was lost.
pytests are running
