5/5 Test #5: projecting .......................***Failed    0.17 sec

ctest.log

Hotfix below didn't improve if I didn't overlook results:

--- a/test/unit/projecting.cpp
+++ b/test/unit/projecting.cpp
@@@ -13,7 -13,7 +13,8 @@@ TEST(Projecting, PCA

      TapkeeOutput output;

--    ASSERT_NO_THROW(output = tapkee::initialize().withParameters((method = PCA, target_dimension = 2)).embedUsing(X));
++    const auto tapkee_obj = tapkee::initialize().withParameters((method = PCA, target_dimension = 2));
++    ASSERT_NO_THROW(output = tapkee_obj.embedUsing(X));

      auto projected = output.projection(X.col(0));
      ASSERT_EQ(2, projected.size())

I didn't get around it yet as I would have liked, so I added it here. From tomorrow I have more time again and I am aiming at getting it going this week. 🤓
