Catch2 - 未定义的引用

我正在使用 Catch2 作为库来测试我的项目。我遵循了 Catch 文档中的每个步骤，但是当我运行测试时，出现以下错误：

CMakeFiles/tests.dir/tests/IntegerIntervalTest.cpp.o: in function "____C_A_T_C_H____T_E_S_T____0()": /home/davide/cpp-project/tests/IntegerIntervalTest.cpp:8: undefined reference to "domain::IntegerAbstractInterval<int, int>::IntegerAbstractInterval(int, int)"

对于测试“类”中的每个方法调用，都会重复此错误。
