Problem with out of tree build

[aleblanc30]

Hi ! I'm trying to add a binding that gives access to energies from python (see sofa-framework/SofaPython3#504)

To test it, I want to build the plugin out of tree. However, there seems to be a problem with the tests that I don't understand. It does not seem to be related to my changes to the code. Any help would be much appreciated !

Here is my cmake command and its output :

build cmake -S $HOME/workspace/SofaPython3/src/SofaPython3 -B . -DCMAKE_PREFIX_PATH=$HOME/workspace/sofa/install/lib/cmake -DCMAKE_CXX_FLAGS=-std=c++20 -DCMAKE_CXX_COMPILER=g++-10 -Dpybind11_ROOT=$(python3.10 -m pybind11 --cmakedir) -DPython_EXECUTABLE=python3.10

And here is the error message from the make step :

To solve your issue, if you are not interested in building the tests, you can deactivate them by adding -DSP3_BUILD_TEST=OFF to your cmake call.
