<p>You shouldn't add the file here, but instead as its own executable, otherwise <code>softmax_main.cpp</code> will get compiled into <code>libmlpack.so</code>, which is not the right thing. Try this instead:</p>
<pre><code>add_executable(softmax_regression
softmax_regression_main.cpp
)
target_link_libraries(softmax_regression
mlpack
)
install(TARGETS softmax_regression RUNTIME DESTINATION bin)
</code></pre>
