Description

Currently able to build libopennn.a just fine, but examples fail (as well as my project one of my current projects, which has opennn as a dependency)

Steps to Reproduce

• cd <opennn repo root>
• cmake . -DOpenNN_BUILD_EXAMPLES=on -DOpenNN_BUILD_TESTS=off -DOpenNN_BUILD_BLANK=off
• make simple_approximation -j

Output:
